A UNIQUE SPECIAL MINT SET ISSUE
During 1965–1967, the United States Mint produced Special Mint Sets (SMS) instead of traditional proof or mint sets. These coins were struck with improved finishes and stronger detail compared to normal circulation strikes.
The obverse features Gilroy Roberts’ portrait of President John F. Kennedy, while the reverse displays Frank Gasparro’s Presidential Seal design.
This particular coin is notable for its Doubled Profile error, where a visible doubling appears along Kennedy’s profile — one of the most recognized varieties among collectors.
