Littlemg2 Pillar of the Community United States 552 Posts	Posted 03/16/2025 7:08 pm according to the US Coin Weight Tolerance 1983-NOW is Lincoln Cent .01 1983 - Now 2.500 (.100) (2.400 low) (2.600 High) 97.5% Zn,2.5% CU yes the coin is poo but is for me trying to make sure I understand the Weight Tolerances for US coins. What do you guys think Science project? Melted? as I have seen coins pretty rough and still weigh as they should. Report this Post to the Staff

Dearborn Moderator United States 98745 Posts	Posted 03/16/2025 8:08 pm as do I, Hondo most likely has the best answer. Collecting since 1972. Learning from then on "Tell me and I forget.

Sap Moderator Australia 16873 Posts	Posted 03/17/2025 9:07 pm I'd assume this is a "fountain coin", or otherwise sat submerged in water for an extended period. Parts of the zinc core corroded and the corrosion products simply dissolved away into the water, reducing the mass. The copper shell is insoluble in water, and has preserved much of the coin's original detail despite no longer being supported by the underlying metal. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
