Interesting Facts About the U.S. Proof Sets:
 Each U.S. Proof set includes doublestruck, mirrorfinish specimens of all U.S. coin denominations issued for that date.
 Their limited mintages make these proof coins "one in a thousand" in relation to regular circulation coins. And the only way these proofs were originally released was in complete denomination sets.
 Substantially fewer complete proof sets are available today than their original mintages suggest because U.S. proof sets are often broken up by collectors and dealers to obtain individual coins.
 The market for U.S. proof sets has grown enormously since the series was revived in 1950. Irregularly issued earlier sets now sell in the thousands of dollars.
