davesmith87 New Member United States 15 Posts	Posted 03/19/2022 7:25 pm Hello all, I went through and weighed at least 1000 1983 pennies today that I have been saving. All were within tolerance of the 2.5g but one. This penny is weighing 2.96g (closer to tolerance within copper then zinc). What are your thoughts? Am I getting excited over nothing?

davesmith87 New Member United States 15 Posts	Posted 03/19/2022 7:32 pm More then that today. Also weighted at least 1000, 1989 pennies as well I had been saving. It was time consuming for sure. Report this Post to the Staff

ijn1944 Bedrock of the Community United States 19304 Posts	Posted 03/19/2022 8:53 pm Given the images posted, it appears your coin has some corrosion/crud on it. Perhaps the crud + a coin at the high end of acceptable tolerance yielded the 2.96 grams. Closer-in, large and sharp photos might tell us more. Report this Post to the Staff
BadThad Bedrock of the Community United States 19988 Posts	Posted 03/20/2022 12:55 am There's a chance it's copper. I don't see any zinc bubbles - need some closer and cropped pictures. I would be surprised if the corrosion added a full half gram to the weight. The very bad - black cupric oxide is permanent and cannot be removed without damaging the coin. If it is copper, the value would be greatly reduced for corrosion at this level. Drop this coin on hard surface and listen for a ping rather than the thud of a zincoln. Coppers and zincs sound completely different It's an easy test. Lincoln Cent Lover! VERDI-CARE™ INVENTOR https://verdi.care/ Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 03/23/2022 7:40 pm I would agree, this weight is close enough to the tolerance of a copper cent to be worth the alternate test. And in the case of this coin a drop test isn't going to cause any/enough damage to reduce the value any further if it is copper. Good luck Davesmith. Report this Post to the Staff
