The Origin of the Kennedy Half Dollar

- First year of minting: 1964
- 90% silver content (1964 only)
- Designed by Gilroy Roberts (obverse) and Frank Gasparro (reverse)
- Face value: 50 cents
Collectors instantly fell in love with the coin not only for its emotional significance but also for its high silver content and beautiful design.

What Makes a Kennedy Half Dollar Valuable?
While millions of Kennedy Half Dollars were minted, only a small percentage hold extremely high value. Here are the key factors that determine the worth of your coin:
- Year of minting (especially 1964 and early 1970s)
- Mint mark (Denver ‘D’, San Francisco ‘S’, or Philadelphia – no mark)
- Error coins (double dies, missing elements, or off-center strikes)
- Condition (uncirculated or proof coins in mint state)
- Silver content (1964 = 90% silver; 1965–1970 = 40% silver)
