The weight of a United States quarter made of 90% silver is a key identifier. These quarters, often referred to as “silver quarters,” were minted before 1965. A standard silver quarter weighs 6.25 grams, or approximately 0.22 ounces. This weight is distinct from modern clad quarters, which are composed of a copper-nickel alloy.
Knowing the weight allows for quick verification of silver content in older U.S. quarters. This is crucial for collectors and investors, as silver has intrinsic value that significantly exceeds the face value of the coin. The historical context is that pre-1965 U.S. coinage contained a high percentage of silver, making them valuable assets due to their precious metal content.
