how much silver is in a quarter

[McAlejandro]

The provided search results do not contain the specific information needed to answer your question. Drawing upon established numismatic knowledge, the amount of silver in a U.S. quarter depends entirely on the year it was minted.

For quarters minted in 1964 or earlier, the composition is 90% silver and 10% copper. These coins are often referred to as "silver quarters" or "junk silver" by investors and collectors. A standard U.S. silver quarter contains approximately 0.18084 troy ounces of pure silver. The total weight of the coin is 6.25 grams, with the silver content accounting for 5.625 grams of that weight.

Beginning in 1965, the United States Mint removed silver from circulating quarters due to the rising cost of the precious metal. Quarters minted from 1965 to the present day are made of a clad composition, consisting of a pure copper core with an outer layer of 75% copper and 25% nickel. Therefore, any quarter you find in common circulation today does not contain any silver, unless it is a pre-1965 coin. Some modern proof sets and special commemorative quarters intended for collectors are struck in silver, but these are not intended for general circulation.
