how much does a quarter weigh?

TLDR: A standard U.S. quarter weighs 5.67 grams (0.2 ounces) and is made of a copper-nickel blend. Historically, quarters have undergone various changes in weight and composition, transitioning from silver to clad coins.

The weight of a quarter has evolved significantly since its introduction in 1792. Initially, silver quarters weighed 6.74 grams but were reduced to 6.22 grams in 1853 and slightly increased to 6.25 grams in 1873. The major shift occurred in 1965 when clad quarters were introduced, made of a copper-nickel blend, resulting in a standard weight of 5.67 grams (0.2 ounces). This change was driven by the rising cost of silver and the need for more economical coin production.

Today, the U.S. Mint maintains this weight to ensure consistency in transactions and machine operations. Additionally, silver proof quarters are produced for collectors, weighing 6.343 grams due to their higher silver content. The standardization of coin weights is crucial for preventing fraud and ensuring the smooth operation of businesses that handle large quantities of coins.
