Historical Significance
California was the 31st coin released in the 50 State Quarters Program and the first issued for 2005. The design reflects California’s admission to the Union in 1850 and pays tribute to John Muir’s legacy in conservation, along with the enduring symbolism of Yosemite National Park and the California condor.
Collectibility
This clad proof issue is a strong choice for collectors building complete State Quarter proof runs, California-themed sets, or modern U.S. Mint proof collections. Its dramatic reverse design, San Francisco proof format, and large collector base make it a popular modern quarter for type and series collectors alike.
