2003 Mint Proof Set, 10 Coins Inside!. Original packaging: The 2003-S Proof Set comes in two cases. One case contains the Cent, Nickel, Dime, Half Dollar and Dollar; the other case contains the year’s five 50 States Quarters. The coins are inserted into holes in a cardboard holder with a blue-colored flag design (to distinguish it from the red-colored flag design of the Silver Proof Sets), then sealed inside a two-piece, clear plastic case. The cases and certificates of authenticity were inserted into a colorful, card-stock box with the head of the Statue of Liberty printed on the left side.
