[QUOTE="V. Kurt Bellman, post: 3035151, member: 71723"]There are three binary factors in 1982 cents in circulation, which would normally mean 8 outcomes - 2x2x2=8. (mint mark, small or large, metal) But there are only 7 combinations that are widely known. There is believed to be only ONE example of that eighth combination. The rare/impossible combo is: DENVER, SMALL DATE, BRONZE Now why? Because the Denver Mint had already stopped using bronze planchets before the small date dies arrived from Philadelphia. Couldn't a shipment get mixed up? No, because mints punched out their own bronze blanks in-house from roll stock, and zinc blanks arrive already pre-punched out. If you "have one", you have EITHER a heavy zinc coin, or it is NOT a small date. (Or you misweighed it - the weight is not the big thing, the metallic composition is. A supposed Denver small date that is heavy ONLY means it needs further study, not that it is a "hit".) Now, let's talk probability for a moment. The mintage of 1982-D cents is a few million over [I][B]6 billion, and ONE SD bronze has been found.[/B][/I] Imagine how unlikely it is you have the second one, found by no one else over 36 years. C'mon, my man, think. I guess you buy Powerball tickets regularly, huh?[/QUOTE]
