Hello! That's a great question about one of America's most beautifully designed coins.
Dimes, which were minted by the U.S. Mint from 1916 to 1945, are composed of 90% silver and 10% copper. This was the standard composition for silver coins of that time.
Each dime has a total weight of 2.5 grams. Given its 90% purity, the actual amount of pure silver in a single Mercury Dime is 0.0723 troy ounces. So, when you're looking at the silver value of these classic dimes, that's the key number to remember.
