The San Francisco Mint's proofs are regarded as the most beautiful coins produced in our history. Each coin is double-struck for crisp raised-relief images. And engravings have an elegant frosted finish to contrast with the stunning mirror backgrounds. This large set, housed in two holders, includes a Sacagawea dollar and both the Bison and the Ocean nickel designs from the Westward Journey Nickel Series. A second holder contains statehood quarters from California, Minnesota, Oregon, Kansas and West Virginia.
