2003 Proof and Mint Set Pair. The U.S. Mint's popular 50 State quarter series increased the size of yearly proof and mint sets. The 10-coin 2003 proof set's 2.2 million mintage was lower than any regular proof set in the previous few years. Included are stunning proof specimens of all the year's circulation coins.
With a production of just over 1.0 million, the big 20-coin 2003 mint set had the second lowest production from 1965 to that date. This sizable set includes both the Philadelphia and Denver mint circulating coins for the year.
These sets contain the special 2003 one-year statehood quarters honoring Illinois, Alabama, Maine, Missouri and Arkansas. Also included are the Lincoln cent, Jefferson nickel, Roosevelt dime, Kennedy half dollar and Sacagawea dollar.
