The U.S. Mint Releases Its First Curved Coins
On March 27, 2014, the United States Mint released one of the most technically unusual commemorative programs in its history: the National Baseball Hall of Fame coins, the first curved coins ever produced by the U.S. Mint. Each coin was shaped like a shallow bowl, with a concave obverse depicting a baseball glove and a convex reverse resembling the surface of a baseball. Issued in $5 gold, $1 silver and clad half-dollar versions for the Hall of Fame's 75th anniversary, the program combined an open national design competition, unprecedented Mint engineering and America's national pastime. The result was a coin whose physical shape became part of its artwork.

March 27, 2014
At noon Eastern Daylight Time on March 27, the United States Mint opened sales for the 2014 National Baseball Hall of Fame Commemorative Coin Program.
The Mint simultaneously celebrated the release on Capitol Hill and sold coins at the Whitman Coin and Collectible Spring Expo in Baltimore.
The Mint promoted the program as its first curved coinage.
The coins were not merely ordinary flat pieces carrying an illusion of depth.
Their metal surfaces were physically curved.
The heads side is concave.
It forms a shallow depression.
Inside that depression appears a baseball glove.
The tails side is convex.
It bulges outward like the surface of a baseball.
The reverse design depicts a baseball.
A flat coin could show a picture of a glove and a ball.
The 2014 commemoratives went further.
The concavity helps the obverse feel like a glove waiting to receive a ball.
The convexity helps the reverse itself resemble a ball.
Every struck coin is technically a relief sculpture.
But the Baseball Hall of Fame coins extend that idea beyond the design relief into the overall geometry of the planchet.
The unusual shape did not begin as an afterthought at the Mint.
The National Baseball Hall of Fame Commemorative Coin Act specifically encouraged the Secretary of the Treasury to create a convex reverse and concave obverse.
President Barack Obama signed the legislation on August 3, 2012.
The law authorized a three-coin commemorative program honoring the National Baseball Hall of Fame.
The National Baseball Hall of Fame and Museum opened in Cooperstown, New York, on June 12, 1939.
The 2014 program marked its 75th anniversary.
Congress's findings named five members of the inaugural class:
- Ty Cobb
- Walter Johnson
- Christy Mathewson
- Babe Ruth
- Honus Wagner
The legislation treated the Hall of Fame as more than a sports museum.
It emphasized baseball's place in American history, education and culture.
Three Denominations
Congress authorized a $5 gold coin, a $1 silver coin and a clad half dollar.
Each carried the same basic glove-and-baseball design concept.
The gold piece was authorized with a maximum mintage of 50,000.
It weighed 8.359 grams and contained 90 percent gold.
It was produced at the West Point Mint.
The silver dollar was authorized up to 400,000 pieces.
It weighed 26.73 grams and measured 1.5 inches in diameter.
Its composition was 90 percent silver and 10 percent copper.
It was struck at Philadelphia.
Congress authorized as many as 750,000 half dollars.
The proof version was produced at San Francisco.
The uncirculated version was struck at Denver.
All three denominations were offered in both proof and uncirculated finishes.
That created six principal collector products.
The common design created an unusual comparison.
Collectors could study how the same curved artwork behaved in gold, silver and copper-nickel clad formats.
Producing a normal commemorative coin is already demanding.
Producing a curved coin introduced new manufacturing variables.
According to the U.S. Mint, research and development for the curved Baseball Hall of Fame coins was unprecedented in its recent history.
The Mint studied height-of-relief limitations.
A design already sits above and below a coin's field.
When the entire coin surface is curved, those relief relationships become more complicated.
The Mint investigated milling, turning and grinding operations needed to create the dies and tooling.
Ordinary flat-coin assumptions could not simply be carried over unchanged.
A design can look excellent in artwork yet fail when struck into metal.
The Mint had to determine whether the curved forms could fill properly under striking pressure.
Proof coins require carefully prepared dies and planchets.
The Mint studied laser frosting and proof polishing on the curved surfaces.
The three denominations did not merely differ in color.
Different alloys, diameters and thicknesses respond differently to striking pressure.
Each format required testing.
Proof, uncirculated and clad test strikes formed part of the development program.
The engineering team had to make the concept manufacturable at production scale.
The U.S. Mint consulted the Royal Australian Mint and Perth Mint for technical insight.
Those institutions had experience with nontraditional curved coin forms.
The authorizing legislation referenced the convex-and-concave 2009 International Year of Astronomy coins issued by the Monnaie de Paris.
The American program therefore belonged to a broader international experiment in shaped modern coinage.
The U.S. Mint says its baseball commemoratives were also closely modeled on Royal Australian Mint Southern Cross curved coins.
Borrowing Technology Is a Mint Tradition
This was not unprecedented in American coinage history.
Franklin Peale had traveled to Europe in the 1830s to study advanced minting machinery before helping introduce steam coinage at Philadelphia.
When another mint has solved a difficult manufacturing problem, studying its experience can accelerate innovation.
Coinage technology has always crossed national borders.
The Mint notes an important distinction.
Although the 2014 issues were its first curved coins, it had previously produced a curved Congressional Gold Medal honoring baseball great Roberto Clemente in 1973.
A Congressional Gold Medal is not legal-tender coinage.
It does not carry a denomination and is not issued under the same monetary framework.
The 2014 program therefore still represents a genuine U.S. coinage first.
Congress required a juried competition to select the common obverse design.
The image had to be emblematic of the game of baseball.
The United States Mint opened the competition from April 11 through May 11, 2013.
It was the Mint's first public design competition since 1992.
Artists from across the country submitted 178 proposals.
They had to consider not only artistic merit but how the image would translate into a curved coin.
Five Hall of Fame members participated in evaluating semifinalist designs:
- Joe Morgan
- Brooks Robinson
- Ozzie Smith
- Don Sutton
- Dave Winfield
Mint sculptor-engravers and a Bureau of Engraving and Printing banknote designer scored entries for artistic merit and suitability for coinage.
Finalist designs were reviewed by the U.S. Commission of Fine Arts and the Citizens Coinage Advisory Committee.
The Hall of Fame also provided input.
The Treasury selected a design by Cassie McFarland of San Luis Obispo, California.
She was still in her twenties.
McFarland chose one of baseball's simplest and most universal objects.
The glove does not belong to a particular team, player or era.
It represents the act of playing baseball itself.
This is the design's greatest strength.
A baseball glove naturally forms a pocket.
The inward curve of the coin reinforces that shape.
The Mint describes the combination of glove and ball as evoking the most basic elements of baseball—a game of catch in a backyard or on a local sandlot.
A collector does not need to recognize a particular stadium or player.
The glove and ball are immediately understandable.
The glove side includes:
- LIBERTY
- IN GOD WE TRUST
- 2014
U.S. Mint sculptor-engraver Don Everhart designed the baseball reverse.
The convex surface made the baseball appear especially natural.
A baseball's stitching is already a raised and tactile feature.
Translating it into coin relief on a curved surface creates a remarkably direct correspondence between object and image.
The Reverse Inscriptions
The baseball side carries the national and denominational inscriptions appropriate to each coin, including UNITED STATES OF AMERICA and E PLURIBUS UNUM.
Turn the coin from one side to the other and the concept becomes clear.
One side is the receiving glove.
The other is the ball.
Usually a coin's shape is simply the canvas.
Here, the shape participates in the illustration.
McFarland was not a longtime Mint engraver or famous medallic sculptor.
She was a young outside artist whose public-competition entry became federal coinage.
The law deliberately opened the obverse to competition rather than limiting the design process to existing Mint artists.
The winning designer received compensation under the competition rules.
More importantly, her artwork became part of U.S. numismatic history.
Design elements were revealed during 2013 as the Mint prepared the program.
But March 27, 2014 is the crucial calendar date because that is when the finished coins actually went on sale.
The Hall of Fame and Mint held a launch event in Washington.
Joe Morgan and Brooks Robinson joined Treasurer of the United States Rosie Rios and congressional sponsors.
Senator Kirsten Gillibrand of New York and Representative Richard Hanna of New York helped sponsor the legislation.
Cooperstown's location in New York made the state's congressional interest natural.
The Whitman Coin and Collectible Spring Expo began the same day at the Baltimore Convention Center.
The Mint sold a limited supply of the new commemoratives at its booth.
The Baltimore Orioles legend and Hall of Fame third baseman supported the release at the Mint's booth.
Baseball fans and coin collectors converged around the same product.
On March 26, the day before launch, the Mint announced household order limits because feedback indicated unusually heavy interest.
The March 24 sales announcement stated there would be no household ordering limit.
That changed within two days.
Proof and uncirculated $5 gold coins received limits of 50 each.
The Mint attempted to distribute the expected demand across more customers.
Publicity around the curved shape and baseball theme generated collector excitement before noon on March 27.
With a maximum authorization of 50,000, the gold denomination had the smallest potential population.
Strong early demand made scarcity concerns immediate.
At 38.1 millimeters, the silver dollar offered a broad canvas for the curved glove and baseball designs.
Its lower cost than gold also made it accessible to more collectors.
The Mint lists the coin at 26.73 grams and 38.10 millimeters in diameter, with 90 percent silver and 10 percent copper composition.
Its overall curved height reached approximately 0.243 inch.
That Height Measurement Is Unusual
Flat coins are generally discussed by diameter, thickness and weight.
A curved coin makes overall height a much more conspicuous engineering specification.
The smaller $5 gold piece could not simply use the silver dollar tooling at reduced scale.
Its curve, relief and strike had to work within a much smaller diameter.
The half dollar used the standard clad specifications required by law.
Producing the curved form in a layered clad composition created another manufacturing challenge.
West Point handled gold.
Philadelphia handled silver.
San Francisco struck proof halves.
Denver struck uncirculated halves.
The geographic spread of production is fitting.
The program celebrated a sport embedded across American communities.
Congress authorized surcharges above the coins' production costs and face values.
The money was designated for the National Baseball Hall of Fame.
Each $5 gold coin carried a $35 surcharge.
Each silver dollar carried a $10 surcharge.
Each clad half dollar carried a $5 surcharge.
The beneficiary is an independent nonprofit educational institution.
Congress viewed the commemorative program as a way to support its work.
They have legal-tender face value.
Precious-metal versions have intrinsic metal value.
Collectors pay a numismatic premium.
A surcharge can additionally support the designated beneficiary.
A $1 silver coin was never intended to be spent for one dollar.
Its collector price reflected silver, manufacturing, packaging, surcharge and numismatic demand.
These coins are genuine United States money.
But they were created for collectors rather than everyday commerce.
The unusual shape was possible precisely because the coins were commemoratives.
A mass-circulation denomination faces stricter requirements for vending machines, counting equipment and high-speed handling.
Special programs allow the Mint to experiment with techniques that would be impractical for billions of circulating coins.
Other commemorative programs have explored unusual finishes, color, high relief and novel packaging.
Collectors often encounter new Mint technology first through special products.
The successful curved format demonstrated that the Mint could manufacture non-flat legal-tender coins at commercial collector scale.
Five years later, the Mint returned to curved coinage for the Apollo 11 50th Anniversary program.
The concave obverse represented an astronaut's footprint while the convex reverse recreated the reflection in Buzz Aldrin's helmet visor.
Just as the baseball coin used convexity to imitate a ball, the Apollo coin used it to imitate a curved helmet visor.
The technology served the subject rather than existing as a gimmick.
The Mint again used curved coins for the Naismith Memorial Basketball Hall of Fame program.
The convex reverse naturally resembled a basketball.
Baseball Established the Template
Once the Mint solved the manufacturing problems in 2014, later programs could build on that knowledge.
The first curved coins were important not merely because they were unusual collectibles.
They expanded the Mint's technical vocabulary.
Traditional coin designers work with diameter, relief, texture and inscriptions.
Curved coinage adds overall surface geometry to that toolkit.
A curved coin that does not reinforce its subject risks becoming novelty for novelty's sake.
The Baseball Hall of Fame design succeeds because the shape has an obvious narrative purpose.
The entire concept can be understood physically.
Concave equals glove.
Convex equals ball.
The engineering was complicated.
The visual idea was simple.
Great industrial design often works that way.
Collectors generally protect proof surfaces carefully, but the unusual shape naturally makes people want to turn the coin and examine its profile.
Viewed from the side, the curvature becomes obvious in a way a photograph of one face cannot fully convey.
Curved reflective surfaces create unusual lighting challenges.
Photographing the proof coins without glare requires careful positioning.
Third-party grading services also had to encapsulate the curved coins securely.
Novel Mint formats ripple through the entire numismatic industry.
A curved piece may not fit ordinary storage products intended for standard flat commemoratives.
Collectors therefore have to consider preservation differently.
Original capsules and presentation materials were designed to protect the unusual shape.
Complete packaging can remain desirable to collectors.
The broad mirrored fields of proof versions can show fingerprints and hairlines easily.
The temptation to touch the curve should be resisted unless the coin is protected.
The program attracted both traditional numismatists and baseball collectors.
That crossover audience was unusually broad.
A baseball fan who had never collected coins could understand the appeal immediately.
A coin collector who cared little about sports could appreciate the technical first.
Baseball connects to family memories, local teams, childhood games and national history.
The glove design intentionally taps that shared experience.
This was a wise choice.
Putting Babe Ruth or another superstar on the coin would inevitably privilege one era or fan base.
A glove and ball belong to everyone who has played the game.
The coin does not rely on a building façade.
It commemorates the institution by representing the game the institution preserves.
Buildings change.
Logos change.
A glove and baseball remain instantly recognizable.
The law constrained one side while opening the other to competition.
This created an interesting balance between legislative direction and artistic choice.
Congress specifies subjects and inscriptions.
Advisory bodies review designs.
Treasury makes final selections.
Mint engineers determine what can actually be struck.
The Baseball Coin Shows the Entire Process
Congress supplied the concept.
A public artist supplied the glove.
Mint artists supplied the reverse and sculptural translation.
Engineers solved the curvature.
Collectors completed the process by buying the coins.
No single person can reasonably be called the sole creator of the finished program.
Modern coinage is institutional art.
Opening the obverse to the public allowed an artist outside the normal Mint design staff to enter national coinage history.
Only one design won.
But the competition itself broadened public participation in federal coin design.
The Mint's own publicity naturally leaned into phrases like “batter up” and “home run.”
Few commemorative programs have offered such irresistible wordplay.
Behind the playful marketing was a difficult manufacturing program.
The curved coins had to meet legal weight and composition standards while also striking reliably and attractively.
Weakly filled baseball seams, distorted lettering or inconsistent curvature would have undermined the entire concept.
The technical execution had to be convincing.
Once a finished curved coin exists in a holder, it can seem inevitable.
It was not.
The Mint had to invent a practical production process.
Numismatic history often focuses on designers and mintages.
Manufacturing history explains how the object became possible.
Every design must survive enormous striking pressure.
Metal has to flow into die cavities.
Tool steel has to withstand repeated impacts.
Dimensions must remain within tolerance.
The unusual shape reminds collectors that a coin is not merely artwork printed onto metal.
It is a precision-manufactured three-dimensional object.
March 27, 2014 was the day the experiment became a public product.
After legislation, competition, design selection, engineering and test strikes, collectors could finally buy America's first curved coins.
For more than two centuries, federal coins had overwhelmingly presented flat fields within round planchets.
The Baseball Hall of Fame program deliberately broke that visual expectation.
A baseball is round.
A glove forms a pocket.
The coin itself became both.
On March 27, 2014, the United States Mint opened sales for the National Baseball Hall of Fame Commemorative Coin Program, releasing the first curved coins in U.S. Mint history. The common obverse, designed by public-competition winner Cassie McFarland, showed a baseball glove on a concave surface; Don Everhart's reverse depicted a baseball on a convex surface. Offered as $5 gold, $1 silver and clad half-dollar coins, the program required unprecedented Mint research into relief, tooling, polishing and coinability. The successful result proved that the physical shape of an American coin could become an active part of its design—and later paved the way for additional curved U.S. commemoratives.
