Each quarter retained its traditional portrait of Washington on the front, while the reverse carried imagery unique to each state. In California’s case, this was a scene with naturalist John Muir gazing on Yosemite with a California condor overhead. Every state created their own design, which was then approved by its governor before finally being issued by the U.S. Mint. The California Quarter was designed by Alfred Maletsky and engraved by Don Everhart.
