The Kennedy Half Dollar Loses Its Silver
On February 3, 1971, the Denver Mint began producing a fundamentally different Kennedy half dollar for circulation. For the first time, the denomination contained no silver at all. The new copper-nickel clad coin ended a centuries-old precious-metal tradition for the circulating half dollar—and the U.S. Mint hoped it would finally persuade Americans to stop hoarding Kennedy halves and put them back into everyday use.

When the presses started at Denver on Wednesday, February 3, 1971, the coins coming off them looked familiar.
John F. Kennedy’s portrait still filled the obverse. The presidential seal-inspired eagle remained on the reverse. The denomination was still fifty cents, and the coin was still unmistakably a Kennedy half dollar.
But inside, everything had changed.
The United States Mint announced that day that Denver had begun producing the new cupro-nickel clad Kennedy half dollar authorized under the 1970 coinage law. Instead of silver, the new circulation coin consisted of copper-nickel outer layers bonded to a pure copper core.
It was the first Kennedy half dollar struck for general circulation since December 1969, according to Mint Director Mary T. Brooks.
More importantly, it marked the end of silver in the regular circulating half dollar.
The Kennedy Half Dollar Had Started as a Silver Coin
The Kennedy half dollar was born in extraordinary circumstances.
President John F. Kennedy was assassinated on November 22, 1963. Almost immediately, the federal government began considering a circulating coin that would honor the fallen president.
The half dollar was selected, replacing Benjamin Franklin’s portrait only fifteen years after the Franklin half dollar had debuted.
Chief Engraver Gilroy Roberts adapted a Kennedy portrait he had previously created for a presidential medal. Frank Gasparro designed the reverse around the presidential seal, with a heraldic eagle surrounded by a ring of stars.
The first Kennedy half dollars appeared in 1964.
Those original coins were struck in the traditional composition used for U.S. dimes, quarters and half dollars of the period: 90 percent silver and 10 percent copper.
That made the 1964 Kennedy half dollar both a memorial to a recently assassinated president and a substantial silver coin. Either factor might have encouraged people to save it. Together, they made widespread hoarding almost inevitable.
Americans Did Not Want to Spend Them
The Kennedy half dollar quickly became one of the clearest examples of a coin disappearing from circulation even while the Mint was producing enormous quantities.
Millions of Americans wanted a Kennedy half as a keepsake. Banks faced heavy demand as soon as the coins were released. Many pieces went directly from bank counters into drawers, collections and family keepsake boxes instead of returning to commerce.
At the same time, the United States was confronting a broader coin shortage and a rising market price for silver.
The government responded with the Coinage Act of 1965. Silver was eliminated from circulating dimes and quarters, which changed to copper-nickel clad construction. The half dollar received a compromise composition rather than losing silver entirely.
Beginning with the 1965-dated Kennedy half dollar, the coin contained 40 percent silver overall.
Its construction was itself a form of clad coinage: silver-bearing outer layers were bonded to a core with a higher copper content. The coin looked broadly similar to the 1964 issue but contained much less precious metal.
The compromise did not solve the circulation problem.
Even 40 Percent Silver Was Enough to Keep Half Dollars Out of Circulation
By the late 1960s, the Kennedy half dollar had developed a peculiar monetary problem.
The Mint was making the coins, but the public was not circulating them normally.
In its February 3, 1971 announcement, the United States Mint stated that approximately 1.2 billion Kennedy half dollars had been produced since 1964. Yet Mint Director Mary T. Brooks acknowledged that there was still a shortage of the denomination in circulation.
She identified several reasons: sentimental attachment to Kennedy, hoarding for bullion value and numismatic interest.
Congress had already attempted to conserve federal silver stocks. The Mint noted that in 1967 Congress limited annual half-dollar production to 100 million pieces in order to conserve government silver supplies.
By 1970, the situation had reached an odd point. No Kennedy half dollars were struck for ordinary circulation with a 1970 date. The Mint reported that 4.6 million pieces were produced that year for proof and uncirculated sets.
If the half dollar was going to return to widespread commerce, policymakers concluded that its remaining silver content had to go.
The legal change came late in 1970.
Public Law 91-607 authorized the removal of the half dollar’s 40 percent silver content. The denomination would move to the same basic copper-nickel clad technology already used for circulating dimes and quarters.
The new half dollar had outer layers composed of copper-nickel alloy bonded to a pure copper center.
For collectors, the easiest visual clue appears along the edge. A copper-nickel clad Kennedy half generally reveals the reddish copper core between the lighter-colored outer layers, unlike the silver-bearing issues that preceded it.
The change also reduced the coin’s weight. The modern copper-nickel clad Kennedy half weighs 11.30 grams, compared with approximately 11.50 grams for the earlier 40 percent silver version and 12.50 grams for the original 90 percent silver 1964 coin.
The design survived. The metal did not.
February 3, 1971: Denver Starts the Presses
The transition became physical reality at the Denver Mint on February 3.
Mary T. Brooks announced from Denver that the facility had begun producing the new copper-nickel half dollars that Wednesday.
The scale of the planned operation was impressive.
The Mint said Denver would produce two million pieces per day.
The goal was not merely to manufacture another annual coin issue. The government wanted enough halves to overcome years of accumulated demand and finally return the denomination to ordinary circulation.
Brooks said the Mint planned to produce the clad half dollars in sufficient quantities to supply all Federal Reserve districts and expressed the expectation that the new composite half dollar would circulate freely in the marketplace.
Philadelphia was scheduled to begin producing the new halves shortly afterward.
Denver, however, was first out of the gate for circulation coinage.
The coin created by that Denver production run is known to collectors as the 1971-D Kennedy half dollar.
It bears the D mint mark identifying the Denver Mint and represents the first year of the copper-nickel clad Kennedy half-dollar type.
Denver ultimately struck 302,097,424 circulation-strike half dollars dated 1971, according to PCGS CoinFacts data. That enormous output is consistent with the Mint’s stated objective of flooding the banking system with enough halves to meet demand.
Philadelphia also produced 1971 circulation strikes, while the San Francisco Assay Office produced proof versions for collectors.
Indeed, the Mint’s February announcement noted that San Francisco had already begun mailing 1971 proof sets in January containing copper-nickel half dollars. That is why February 3 should be described specifically as the beginning of production of the new clad Kennedy halves for circulation at Denver, rather than the first time any 1971 clad Kennedy half had been struck.
What the New Coin Was Made Of
The copper-nickel clad half dollar uses a layered construction rather than a single homogeneous alloy.
The outer layers are 75 percent copper and 25 percent nickel. Those layers are bonded to a core of pure copper. Taken as a whole, the coin contains no silver.
The result is durable, relatively inexpensive and suitable for high-volume circulating coinage.
The same basic clad concept had already proven workable on the dime and quarter following the 1965 coinage reforms.
For the half dollar, however, the change carried greater symbolic weight because the denomination had retained some silver after the dime and quarter abandoned it.
With the 1971 circulation issue, that final link was severed.
Half dollars had been silver coins since the earliest years of the United States Mint.
The first federal half dollars, struck in 1794, were substantial silver pieces. Over the generations the designs changed—from Flowing Hair to Draped Bust, Capped Bust, Seated Liberty, Barber, Walking Liberty, Franklin and Kennedy—but silver remained fundamental to the denomination.
The percentage and legal standards evolved, yet the concept persisted: a half dollar was a silver coin.
That made 1971 a genuine dividing line.
A 1964 Kennedy half belonged to the old 90 percent silver standard. The 1965–1970 issues represented a transitional 40 percent silver era. Beginning in 1971, ordinary circulating Kennedy halves belonged to the copper-nickel clad age.
Collectors can see this entire transformation within a single coin design.
The government’s reasoning was straightforward.
If people were hoarding half dollars because of silver, remove the silver. If shortages persisted because people were saving the coins, make hundreds of millions more. Eventually, the denomination should circulate normally.
But the experiment never fully worked.
The half dollar did not regain the everyday role it had once held in American commerce.
Part of the problem was behavioral. Americans had already become accustomed to not seeing half dollars in routine transactions. Cash registers were built around other denominations, businesses rarely ordered halves from banks, and customers who received Kennedy halves often continued to save them.
The coin’s large size also made it less convenient than two quarters.
So the 1971 composition change solved one problem—the government no longer had to devote silver to ordinary half-dollar production—but it could not reverse the denomination’s declining practical importance.
The Kennedy half became increasingly unusual in pocket change even though it remained an official circulating denomination.
A Common Coin with an Important Story
Because more than 300 million 1971-D half dollars were struck, ordinary examples are not rare.
That makes the coin accessible to collectors who want a physical artifact from this monetary transition.
PCGS describes the 1971-D as common overall, with the real collecting challenge appearing in exceptionally high Mint State grades. Coins intended for mass circulation were handled in bulk at the Mint, transported in bags and subjected to contact with other coins, so pristine surfaces can be much harder to find than the huge mintage might suggest.
This is an important distinction in numismatics: rarity of the date is not the same thing as rarity of condition.
A circulated 1971-D Kennedy half may be inexpensive, yet a superbly preserved example can be significantly more difficult.
The switch to copper-nickel did not require Americans to learn a new-looking half dollar.
Gilroy Roberts’ portrait of Kennedy remained on the obverse. Frank Gasparro’s reverse continued to feature the heraldic eagle adapted from the presidential seal.
This continuity helped preserve the identity of the coin while its physical composition changed dramatically.
It also gives collectors an unusually clear way to study changes in United States coinage policy. A group of Kennedy halves from 1964, the 1965–1970 period and 1971 onward can look very similar while representing three distinct metallic standards.
The portrait remained Kennedy.
The economic assumptions beneath the coin changed.
Why February 3 Matters
February 3, 1971 captures a turning point that is easy to overlook because the coin itself remained visually familiar.
The United States was completing a retreat from silver in ordinary circulating coinage that had accelerated during the shortages and rising metal prices of the 1960s.
The dime and quarter had already changed. The half dollar had been allowed a transitional period with reduced silver content.
Now that period was over.
The Denver Mint’s presses began turning out the new copper-nickel halves at industrial scale, and the government hoped the removal of precious metal would finally transform the Kennedy half from an object people saved into a coin people spent.
History had other plans. The half dollar never truly returned to its old place in everyday commerce.
Yet that makes the February 3 event even more revealing. It shows the limits of what changing a coin’s metal could accomplish. Congress and the Mint could redesign the composition, dramatically increase production and remove the bullion incentive—but they could not force the public to treat the Kennedy half as ordinary pocket change.
For collectors, 1971 begins the familiar copper-nickel clad Kennedy half-dollar type.
The coins produced at Denver on February 3 belonged to a new monetary era: one in which the half dollar’s value came entirely from its legal denomination rather than any meaningful precious-metal content.
That basic construction would define regular Kennedy half dollars for decades.
And so a date that began with a straightforward Mint production announcement became a landmark in American coinage history.
On February 3, 1971, Denver began striking the new copper-nickel Kennedy half dollar for circulation—ending silver in the regular circulating half and beginning the modern clad era of the denomination.
