Some may have spots or natural toning. The US Mint ceased production of 90% silver coins in 1964. Starting in 1992, the mint resumed minting 90% silver dimes, quarters and half dollars exclusively for their annual Silver Proof Sets.These coins are produced to the exact weight and specifications as were 1964 and before 90% silver coins. All of these proof coins bear the S San Francisco mintmark. Most of these coins were produced with a deep cameo appearance. These are exceptionally brilliant, beautiful coins.
Since these coins were only produced for Silver Proof Sets, the mintage numbers are quite low. Important note: These coins were only inspected to verify the year and count. They were not individually inspected to cull for cameos, deep cameos, variations, toned coins, spots or mint errors.
