The deep cameo 1951 Franklin half-dollar proof has a more intricate strike than circulation coins. This coin features a sharp founding father profile with every detail. Condition affects value too. In 2017, an excellent gem plus sample sold for $82,250.
The San Francisco Mint struck only over four million Franklin half dollars in 1953, making them rare.
Since most coins were considered a "weak strike" at the Mint, they're extremely rarer when all the Liberty Bell lines on the reverse are visible and unbroken. A 1953-S with full bell lines may be valuable. In 2024, one sold for $66,000.
The 1953 proof coin is another valuable proof in this series. A coin with a fine strike and a deep cameo with lovely details might be valuable. An excellent gem sold for $63,250 in 2006. It's one of the best specimens of this coin.
Limited-edition proof coins are said to have more detail than normal strikes. The Mint had not made proofs for eight years, and many of the 1950 Franklin half-dollar proofs lacked detail collectors anticipate.
Thus, detailed 1950 proofs are rare and valuable. An exquisite deep cameo sold for $44,650 in 2017.
The Mint packing leaves tiny lines and markings on several 1955 Franklin half dollar proofs. One in perfect condition with fine details and few marks is unusual. One sold for $43,200 in 2021.
Another valuable proof coin is the 1961 Franklin half dollar. Collectors want these unusual deep cameos and clear detailing. Perfect coins are rare. One stunning example sold for $40,800 in 2018.
