The Walking Liberty Half Dollar's Mintmark Is Ordered to Move
On February 14, 1917, United States Mint Director F. H. von Engelken ordered the mintmark on the new Walking Liberty half dollar moved from the obverse to the reverse. His complaint was remarkably specific: the prominent obverse mintmark looked like a defect in the die. The change created one of the most recognizable first-year varieties in twentieth-century American coinage—1917-D and 1917-S half dollars exist with their mintmarks in two completely different locations.
◆
Sometimes a major coin variety begins with a tiny design complaint.
In this case, the problem was a single letter.
The Walking Liberty half dollar had only recently reached the public when Mint Director Friedrich Johannes Hugo von Engelken decided that the branch-mint letters were in the wrong place.
Denver coins carried a D.
San Francisco coins carried an S.
On the earliest Walking Liberty halves, those letters appeared on the obverse beneath the motto IN GOD WE TRUST, behind Liberty.
Von Engelken thought they were too conspicuous.
On February 14, 1917, he verbally ordered them moved.
A New Half Dollar for a New Era
The Walking Liberty half dollar had replaced Charles Barber's long-running half dollar design.
By the 1910s, Treasury officials wanted a more artistic generation of American coins.
The new half dollar was designed by sculptor Adolph A. Weinman, who also created the Winged Liberty Head dime—better known today as the Mercury dime.
Weinman's half dollar became one of the defining designs of the American coinage renaissance.
The obverse shows a full-length figure of Liberty striding toward the rising sun.
She extends her right arm forward.
Her left arm carries branches of laurel and oak, symbols associated with civil and military glory.
The folds of the American flag flow around her.
The word LIBERTY spans the upper rim.
IN GOD WE TRUST appears in the right field.
The date sits below.
The United States Mint still describes Weinman's Walking Liberty as one of the nation's iconic coin designs.
The Eagle on the Reverse
The reverse depicts a bald eagle perched on a rocky crag.
A mountain pine grows from the rock.
The eagle's wings are partially unfolded, giving the bird a sense of readiness and strength.
Above it appears UNITED STATES OF AMERICA.
E PLURIBUS UNUM is placed to the left.
HALF DOLLAR appears below.
The design was unusually sculptural for a circulating coin.
It was also difficult to manufacture perfectly.
The first Walking Liberty half dollars were not struck until late in 1916.
PCGS research places the beginning of production around Thanksgiving.
Coins bearing the 1916 date were struck at Philadelphia, Denver and San Francisco.
Philadelphia coins had no mintmark.
Denver and San Francisco pieces placed their D or S on the obverse.
The mintmark sat beneath IN GOD WE TRUST in the field behind Liberty.
The Walking Liberty half dollar was officially released in January 1917.
Americans were suddenly handling a dramatically different fifty-cent piece.
Barber's restrained Liberty head had been replaced by a full figure moving across the coin.
The change was visually striking.
It also gave Mint officials a chance to evaluate how the design looked in normal use.
One feature quickly bothered the director.
On February 14, 1917, Mint Director F. H. von Engelken verbally ordered the mintmark relocated.
According to Mint correspondence cited by PCGS, von Engelken believed the obverse mintmark had “the appearance of a defect in the die” and was “entirely too prominent.”
The complaint is fascinating because the mintmark was doing exactly what mintmarks are supposed to do: identify the facility that made the coin.
But visually, the director thought it disrupted Weinman's obverse.
The solution was simple.
Move it to the other side.
The Order Was Not Immediately Carried Out
A February order did not mean every mint instantly changed its dies.
Coinage production depended on working dies, die shipments, engraving work and communication between Philadelphia headquarters and branch mints.
Meanwhile, von Engelken's own tenure as Mint Director was ending.
He had taken office in September 1916.
In March 1917, only about six months later, he resigned to become president of the Federal Land Bank of the Third District.
The mintmark relocation still needed to be implemented.
Raymond T. Baker succeeded von Engelken as Director of the Mint.
In April, Philadelphia Mint Superintendent Adam Joyce asked whether the earlier order should still be followed.
Baker confirmed it in writing on April 14, 1917.
The dies were then modified so Denver and San Francisco mintmarks appeared on the reverse.
The new position was near the lower-left edge, around the seven o'clock position, close to the word HALF.
The result was a collector's dream.
Some 1917-D and 1917-S Walking Liberty half dollars had already been struck with the mintmark on the obverse.
Later coins carried it on the reverse.
Therefore four distinct branch-mint issues exist for 1917:
1917-D Obverse Mintmark
1917-D Reverse Mintmark
1917-S Obverse Mintmark
1917-S Reverse Mintmark
They are not subtle die varieties requiring magnification.
The identifying letter literally changes sides of the coin.
On a 1917-D or 1917-S obverse-mintmark half, look to the right of Liberty.
The D or S appears below IN GOD WE TRUST, close to the lower-right field.
This is the same general placement used on the 1916-D and 1916-S Walking Liberty halves.
Every mintmarked 1916 Walking Liberty half uses the obverse position.
That makes 1917 the transition year.
How to Find the Reverse Mintmark
Turn over a later 1917 branch-mint half.
The mintmark appears near the lower-left rim, to the left of HALF DOLLAR and below the pine branch area.
This reverse position became the standard location for the remainder of the Walking Liberty half dollar series.
Once the change was complete, the mintmark never returned to Weinman's obverse.
The Denver obverse-mintmark issue is especially important to collectors.
Only 765,400 were struck before the change.
That is a small production total for a twentieth-century circulating half dollar.
Many entered commerce and became heavily worn.
Problem-free examples in higher circulated grades are consequently much scarcer than a casual look at the series might suggest.
San Francisco's obverse-mintmark production was also limited.
The mintage was 952,000.
Like its Denver counterpart, the coin is a key early Walking Liberty issue.
Collectors seeking a complete date-and-mint set cannot simply acquire “a 1917-S.”
They need both mintmark positions.
Once the dies changed, production continued with the mintmark on the reverse.
Denver struck 1,940,000 reverse-mintmark halves.
San Francisco struck 5,554,000.
The 1917-S Reverse is therefore much more available than the earlier S-obverse issue.
The contrast in mintages helps explain the substantial differences collectors see in availability and value.
Philadelphia coins carried no mintmark.
There was therefore no D or S to relocate.
A normal 1917 Philadelphia half dollar cannot be categorized as an obverse- or reverse-mintmark variety.
The February 14 change matters specifically to Denver and San Francisco coinage.
This is an important distinction for new collectors learning the series.
Why Mintmarks Matter
A mintmark is tiny, but it can transform a coin's identity.
A date tells when a coin was made.
A mintmark tells where.
For many United States series, the combination determines rarity.
A Philadelphia issue might be common while a Denver or San Francisco coin of the same year is scarce.
The 1917 Walking Liberty half adds another layer: collectors must know not only the letter but its location.
Nothing about the mintmark's location altered the coin's denomination, silver content or legal-tender status.
The change did not result from a congressional act.
It did not solve a major mechanical crisis.
It was primarily an aesthetic and administrative decision.
The Mint Director thought the obverse letter looked like a die defect and distracted from the design.
That small judgment created a permanent numismatic distinction.
Collectors love transition years because they reveal change happening in real time.
Sometimes a metal composition changes.
Sometimes a design changes.
Sometimes a denomination disappears.
In 1917, the change was simply the position of a letter.
Yet the surviving coins preserve the sequence.
Place an obverse-mintmark 1917-D beside a reverse-mintmark 1917-D and the Mint's February-April decision becomes visible without reading a single document.
The mintmark was not the only challenge presented by Weinman's design.
Walking Liberty half dollars can be difficult to find with complete strikes.
Liberty's left hand, head and skirt lines are among the areas that often show weakness.
On the reverse, the eagle's feathers can also lack full definition.
The broad, artistic relief that made the design beautiful did not always make it easy to strike.
Collectors therefore judge Walking Liberty halves not only by wear and marks but also by strike quality.
America Entered World War I Weeks Later
The timing gives the 1917 half dollar additional historical resonance.
When von Engelken issued his February 14 order, the United States was still officially neutral in World War I.
Less than two months later, on April 6, 1917, the United States declared war on Germany.
Weinman's Liberty—walking toward the dawn while carrying branches symbolizing civil and military achievement—would circulate through one of the most consequential periods in American history.
The Walking Liberty half dollar remained in production through 1947.
Its thirty-plus-year run carried the design through World War I, the Roaring Twenties, the Great Depression and World War II.
In 1948, Benjamin Franklin replaced Liberty on the half dollar.
The U.S. Mint notes that 1947 was the final year Liberty appeared on a regular U.S. circulating coin before the modern commemorative and special-design era.
The Walking Liberty design did not stay retired.
When the United States introduced the American Eagle bullion program in 1986, Weinman's obverse was revived for the one-ounce American Silver Eagle.
The design became familiar to an entirely new generation of collectors and investors.
The U.S. Mint describes it as one of the most beautiful designs ever used on an American coin.
Modern Silver Eagles have now carried Weinman's Liberty for decades—longer than the original half dollar itself circulated.
The Mint honored the design's centennial again in 2016.
A special half-ounce, 24-karat gold coin reproduced the Walking Liberty half dollar design as part of a centennial program also honoring the Mercury dime and Standing Liberty quarter.
The gold tribute emphasized how enduring the 1916 coinage renaissance had become.
A design once adjusted because its tiny mintmark looked awkward had become a national numismatic icon.
What Collectors Should Check on Every 1917-D and 1917-S
A collector examining a 1917 branch-mint Walking Liberty half should never identify the coin by date and mintmark alone.
The position must be checked.
First look beneath IN GOD WE TRUST on the obverse.
If no D or S appears there, inspect the reverse near the lower-left rim.
The difference is obvious once you know where to look.
It can also mean a substantial difference in rarity and value.
Most administrative orders disappear into archives.
This one survives on millions of coins.
The early 1917-D and 1917-S halves show the original placement.
The later coins show the revised placement.
Collectors can literally hold the “before” and “after” versions of a Mint Director's decision.
That is one of the pleasures of numismatic history: paperwork becomes metal.
February 14, 1917 did not introduce a new denomination.
It did not change silver content.
It did not create a new coin design.
Instead, it changed one tiny detail.
But that detail created four distinct branch-mint varieties within a single year and gave collectors one of the easiest design transitions to see with the naked eye.
It also reveals how closely Mint officials scrutinized the appearance of America's new coinage.
The Walking Liberty half dollar is celebrated for Weinman's sweeping artistry.
Yet one of its best collector stories revolves around a letter no larger than a few millimeters.
Von Engelken thought the obverse mintmark looked like a defect.
He ordered it moved.
The Mint followed through.
More than a century later, collectors still organize 1917 halves around that decision.
On February 14, 1917, Mint Director F. H. von Engelken ordered the Walking Liberty half dollar's mintmark moved from the obverse to the reverse—creating the famous 1917-D and 1917-S obverse- and reverse-mintmark varieties that preserve the change in silver to this day.
