In a discovery that has sent shockwaves through the numismatic world, a long-lost prototype of the 1964 Kennedy Half Dollar has finally emerged from obscurity. Hidden in a family estate for nearly 60 years, this ultra-rare coin is now valued between $175,000 and $250,000, making it one of the most valuable U.S. coins of its kind.
Believed to be one of only two known examples, this prototype was never officially released to the public. Its unexpected rediscovery has reignited interest among coin collectors, investors, and historians—and could potentially change what we know about this iconic coin’s origin.
The Kennedy Half Dollar: Born from Tragedy
The Kennedy Half Dollar was first issued in 1964, just months after the assassination of President John F. Kennedy in November 1963. The U.S. Mint moved quickly to honor the fallen leader, replacing the Benjamin Franklin Half Dollar with a new design featuring Kennedy’s profile.
Chief Engraver Gilroy Roberts and Assistant Engraver Frank Gasparro collaborated on the coin’s design. The obverse displays Kennedy’s dignified portrait, while the reverse retains the presidential seal. The coin was struck in 90% silver, adding to its emotional and intrinsic value.
Millions of Americans kept the coin as a memento, but few knew about the existence of early prototype versions, which were believed to have been lost—or destroyed—before public release.
The Long-Whispered Legend: The Missing Prototype
For decades, rumors persisted within the coin collecting community about a special prototype of the Kennedy Half Dollar. These early test strikes supposedly featured an ultra high-relief design and sharper engraving than the coins released to the public.
Although internal U.S. Mint documents and former employees hinted at the existence of these prototypes, no confirmed examples had ever been authenticated—until now.
Accidental Discovery: A Family’s Hidden Treasure
The rare prototype came to light in the most unexpected way. While cleaning out the belongings of a deceased relative, a family discovered a box filled with old coins, documents, and keepsakes. One coin, a 1964 Kennedy Half Dollar, immediately stood out due to its sharp detail and unusual quality.
At a local coin show, the coin was casually shown to a dealer, who instantly recognized its potential rarity. Upon further analysis by the Professional Coin Grading Service (PCGS), it was confirmed to be an authentic prototype—one of only two believed to still exist.
Why This Kennedy Half Dollar Is So Valuable
1. Ultra Rare Prototype
This coin was never released to the public. It was a part of an experimental test run and features a deep-relief strike, making it a one-of-a-kind artifact from the U.S. Mint’s production process.
2. Historical Significance
The coin’s design predates the official public release of the Kennedy Half Dollar. As such, it holds a unique connection to a pivotal moment in American history—right after the nation mourned the loss of President Kennedy.
