<p>[QUOTE="Surgeprotector, post: 3040158, member: 93826"]So after being intrigued by the weird color 1976 cent I decided to do some more digging. First I found someone else on here had a similar coin and the consensus was that it was plated, so I thought if mine was plated it would weigh more than the other 1976 I had to compare. The result was even more confusing as it weighed less (FYI, I don't have a gram scale, I did the pen and ruler way) than 3.11 grams. So I thought something must have happened in 1976 with the US Mint and decided to search the Library of Congress website for Treasury Reports for the year 1976. After reading the report I found out that the US Mint that year made coins for foreign countries, 800,976,163 coins for Liberia, Panama, Peru, and the Philippines. The only one that they made bronze coins for was Peru though and also the only place it was made was at the Philadelphia Mint. Next step, looked up the Peruvian coins and the only similar one in size was the Peruvian 1/2 Sol de Oro. That coin weighs 2.1 grams and the closest to that weight for me to compare is a Dime (2.5 grams), and wouldn't you know it, at times it was the same or the dime was heavier. Here is my theory that is far from being proven: Could this really be a bronze planchet left over during the minting of the Peruvian coins (color looks so similar in the pictures) - was there a planchet left over and used for the Lincoln Cent? Did the mint test out a Lincoln Cent die to see how the die would work with the bronze Peruvian cent and accidentally add it to the regular circulation coins? I am going to buy a gram scale tomorrow and get some actual weights, I am also goin to track down a Peruvian 1/2 Sol to closely compare. I think we can rule out "plating" due to the cursory weight (will confirm tomorrow) but if anyone has any other ideas or tests for me to try let me know. This should be fun.[/QUOTE]</p><p><br /></p>
