Collectible coins include various types that are sought after by numismatists, such as commemorative coins, bullion coins, and circulating currency with historical significance. The United States of America has produced numerous collectible coins, including the iconic 1 One Dollar coin and Roosevelt Dimes, which were first minted in 1946 to honor President Franklin D. Roosevelt. The 1979 San Francisco mint marks are particularly notable for their limited production and unique characteristics, making them desirable among collectors.
