Silver Dimes
Until 1965, U.S. dimes were composed of 90% silver and 10% copper. However, because of rising silver prices, the U.S. Mint decided to continue debasement of coinage by changing the composition of dimes to a copper-nickel alloy, starting with the clad coin production in 1965. Today’s dimes are composed of 91.67% copper and 8.33% nickel.
Online bullion dealers typically offer 90% silver dimes based on the face value that each contains. For example, a $5 Face Value standard bank roll of silver dimes will contain fifty individual pieces that were minted Pre-1965. Each circulated silver dime contains approximately .0715 troy ounces, with each standard $5 Bank Roll of silver dimes having a total of 3.575 troy ounces ASW.
