Bust Dimes Liberty Seated Dimes Barber Dimes Mercury Dimes Roosevelt Dimes Certified Dimes The dime is a coin worth ten cents or one tenth of a United States dollar. The dime is the smallest in diameter and the thinnest of all U.S. coins currently minted for circulation. The 32nd President, Franklin D. Roosevelt, is featured on the obverse of the current design, while a torch, oak branch, and olive branch covering the motto E pluribus unum are featured on the reverse. The dime's value is labeled as "one dime," since the term 'dime' also applies to a unit of currency worth 10 cents or 1/10 of a dollar.
