Collectible coins include a variety of types, such as the United States five-cent nickels and half dimes. Buffalo Nickels, minted from 1913 to 1938, are particularly sought after, with the 1931-S being one of the rarest and most valuable due to its low mintage in San Francisco. Collectors often focus on factors like condition, rarity, and historical significance when assessing the value of these coins.
