1982 No-P Roosevelt Dime, United States Mint

The 1982 Roosevelt Dime is notable for being the only year in the modern era when Philadelphia Mint dimes were struck without a mint mark, making them particularly sought after by collectors. This occurred due to a production oversight at the Philadelphia Mint, where the 'P' mint mark was inadvertently omitted from the dies. The Roosevelt Dime series was introduced in 1946 to honor President Franklin D. Roosevelt following his death in 1945, and has been continuously minted since then. This particular variety appeals strongly to error coin collectors and numismatists who specialize in modern United States coinage. The 1982 No-P Dime represents a significant modern minting error and is considered one of the key dates in the Roosevelt Dime series. Collectors value these coins for their historical significance as a documented mint error and their relative scarcity compared to standard production dimes.
