How Much Does A Quarter Weigh?

Modern quarter Weight
5.670 grams or (0.200 ounces)

All U.S. quarters (25-cent pieces) minted since 1965 weigh 5.670 grams (0.200 ounces). US quarters have a diameter of 24.66 mm, a thickness of 1.75 mm, and are primarily composed of “clad sandwich” of copper (91.67%) on the inside with nickel (8.33%) plating on the outside.

Prior to 1964, from 1873 to 1964, US quarters were composed of 90% silver and 10% copper, with a weight heavier weight of 6.25 grams, or 0.022 ounces. Even earlier, while the U.S. was in its infancy, the federal government passed the Coinage Act of 1792. This established the U.S. dollar and dictated weights for different coins, including a new 25-cent piece. The new quarter was to be 6.01 grams (0.211 ounces) pure silver, 6.74 g (0.237 ounces) standard silver. These weights lasted from 1972 until the Coinage Act of 1873.
