All of today’s annual U.S. Mint Proof Sets are struck at the San Francisco Mint. These issues are only made available to coin collectors and are not released into circulation. These coin sets consist of that year’s San Francisco proof issue of the penny, nickel, dime, quarters, half dollar, Presidential dollars and Native American dollar.
Struck in very low mintages, United States Mint Proof Sets are highly sought after each year by numismatic collectors. Proof coins are produced with quality in mind as opposed to quantity. Each coin is carefully struck with increased pressure multiple times using specially polished dies and planchets resulting in a highly contrasting mirrored design.
These sets have grown in demand since the Statehood Quarter Program was launched back in 1999. U.S. Proof Sets have become core collectibles in American numismatics. Representing a point in time, U.S Mint Sets are heavily collected in association with dates to remember, birth years, graduations etc.
