Mint engraver Charles Barber designed the first quarters with a Liberty head design, as well as dimes and halves. These “Barber Quarters” were primarily composed of silver and were produced in 1892-1916. The design was changed to a “Standing Liberty” which was produced from 1916-1930. Since then, quarters have featured the profile of the first president, George Washington. As with dimes and halves, silver was primarily used to make quarters through 1964. States, territories, and national parks began being showcased on the reverse of the quarter in 1999.
