The 1956 Denver dime is a collectible coin from the United States, part of the Mercury dime series minted from 1916 to 1945, though it is often referenced alongside the Roosevelt dime series that began in 1946. The 10-cent coin, commonly known as the dime, features the likeness of Liberty on the obverse and a fasces and olive branch on the reverse. Coins from the Denver Mint, indicated by the "D" mintmark, are of particular interest to collectors, especially if they are in high grades or possess unique characteristics, such as errors or varieties. Rolls of these dimes can be sought after by numismatists for both their historical value and potential investment return.
