Dime (United States coin)

The dime, in United States usage, is a ten-cent coin, one tenth of a United States dollar, labeled formally as "one dime". The denomination was first authorized by the Coinage Act of 1792. The dime is the smallest in diameter and is the thinnest of all U.S. coins currently minted for circulation, being 0.705 inches (17.91 millimeters) in diameter and 0.053 in (1.35 mm) in thickness. The obverse of the current dime depicts the profile of President Franklin D. Roosevelt and the reverse boasts an olive branch, a torch, and an oak branch, from left to right respectively. As of 2011, the dime coin cost 5.65 cents to produce.[1]

The word dime comes from the Old French disme (Modern French dîme), meaning "tithe" or "tenth part", from the Latin decima [pars].[2] In the past prices have occasionally been quoted on signage and other materials in terms of dimes, abbreviated as "d" or a lowercase "d" with a slash through it (₫) as with the cent and mill signs. As of 2019, the dime is the only United States coin in general circulation that is not denominated in terms of dollars or cents.
