1stlady19 New Member United States 30 Posts	Posted 03/15/2023 4:42 pm Hello! Found this black dirty penny but it weighs so light, 2.7 on my scale. Can these old Pennie's deteriorate? Thoughts? Report this Post to the Staff

JimmyD Bedrock of the Community Canada 21610 Posts	Posted 03/15/2023 4:49 pm Your scale only goes to one decimal point (it really needs to go to at least two for an accurate weight) so between that, the mint tolerance of +- 2.3g and the fact it has probably lost weight due to some corrosion, it seems to be normal.

dsking Pillar of the Community United States 2365 Posts	Posted 03/15/2023 4:55 pm Anything is possible. I don't know the parameters but, .41 is minuscule and may fall within the reasonable weight parameters. The coin is pretty damaged so that may be the reason for the difference. We have other experts here that would have the parameters. Stay tuned. Oops...just noticed JimmyD's post... Edited by dsking 03/15/2023 4:56 pm Report this Post to the Staff
halfamind Pillar of the Community United States 1489 Posts	Posted 03/15/2023 5:52 pm Yes, worn or damaged coins can lose considerable mass. If you've ever seen a roll of worn Mercury dimes (or any other denomination) beside a "fresh" roll, you'll see the profound difference in stack height. Report this Post to the Staff
1stlady19 New Member United States 30 Posts	Posted 03/15/2023 5:56 pm But wouldn't the words or image be completely gone if it was corroded? It feels soo light. I'm surprised it weighed the 2.7! Lol. Any chance it was struck on another type of coin or silver? Last question. should I clean it to see what's underneath the black? (Bad bad Girl cuz I know better but since it's nothing special, why not?) Report this Post to the Staff

Dearborn Moderator United States 96315 Posts	Posted 03/15/2023 9:19 pm yep, sure looks like it spent some time in unfavorable conditions and lost some weight. It is possible that it started as a planchet that weighed in at the minimum before it lost more. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.
