The current coin is the Washington Quarter (showing George Washington), replacing the Standing Liberty Type, minted from 1916-1930. The present coin, designed by John Flannagan, has been issued since 1932.
It is Cupro-Nickel (8.33% Ni and the balance Cu), weighs 5.670 g, diameter 24.26 mm, width 1.75 mm with a reeded edge. It costs 4.29 cents to produce each coin. Before 1965, quarters contained 90% silver, 10% copper.
The quarter has been in use since 1796.
