Collectible coins, such as the 1940 dimes (10c) from the United States, are sought after by numismatists for their historical significance, rarity, and potential value. These dimes are part of the Mercury Dime series, which features the iconic design by Adolph A. Weinman. Coins from this era can vary in condition and mint mark, influencing their collectibility and market price. Collectors often acquire dimes in rolls, which may contain uncirculated or higher-grade examples, enhancing their desirability.
