Coin and Paper Money Collecting/1984 T aluminum penny


question?  I too have a 1984 D aluminum. government mistake penny.  where to prove this. Ithink by now its clear.   These error pennys are infact real


It's likely an unplated zinc planchet rather than an aluminum cent. The planchets are manufactured by a private firm outside the mint. The zinc planchets (1982 and on) are coated with copper plating before they are sent to the mint for striking. It is hard to tell if they are real, because a method has been developed to remove the coating after it was struck. Real uncirculated examples sell for about $50, but circulated ones go for $15 to $25. You may want to check eBay listings and see what they bring. Take your coin to a local coin shop for them to see, but do not let them cut the edge to see if it's plated, Hope this helps.
