Richard Johnson New Member United States 27 Posts	Posted 06/28/2021 4:43 pm I found this quarter in a coin star machine this afternoon and discovered a possible rim error. I hope these images help. And I trust everyone's opinion about just what this might be. Thanks in advance. RJ A image of the front will not post. Report this Post to the Staff

Oldfordman Pillar of the Community United States 2869 Posts	Posted 06/28/2021 7:17 pm The copper reacts way faster. Copper is a highly reactive metal. Report this Post to the Staff
Earle42 Bedrock of the Community United States 10044 Posts	Posted 06/28/2021 8:53 pm Almost certainly a nitric acid bath did this. I used to make these in my chemistry class so kids would have an object lesson on how nitric acid dissolves metal. Volumes of dark brown gas are given off during the reaction and it makes for a decent spectacle. How much squash could a Sasquatch squash if a Sasquatch would squash squash?

silviosi Pillar of the Community Canada 6244 Posts	Posted 06/28/2021 10:53 pm I will say no nitric acid. Nitric acid reacts with copper according to the reaction: 4 HNO3(l) + Cu(s) ==> Cu(NO3)2(s and aq) + 2 NO2(g) + 2 H2O(l) The copper nitrate salt that forms is a deep blue color. the reaction of nickel oxide with nitric acid: NiO + 2 HNO3 + 5 H2O → Ni(NO3)26H2O. ... Ni(CO)4 + 2 N2O4 → Ni(NO3)2 + 2 NO + 4 CO. The hydrated nitrate is often used as a precursor to supported nickel catalysts. So if was acid like nitric (shore will be less then 100% ) will react with the both metals. I think more to a magician coin. On minting process this kind of error it is 100% impossible.
