John1 Moderator United States 56855 Posts	Posted 07/16/2023 11:53 am Normal weight is 3.24 grams. Looks like a once buried coin. John 1 Report this Post to the Staff

Sap Moderator Australia 16873 Posts	Posted 07/23/2023 05:35 am I'm guessing heavily corroded, then cleaned. Harsh physical or chemical cleaning of heavy corrosion (eg. acid) would reduce the weight, and leave a "moonscape" surface. 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
chgk1628 Valued Member Hong Kong 155 Posts	Posted 07/23/2023 6:41 pm Thanks for your opinion! But if it's due to the chemical or physical heavy corrosion,then all the devices on the obverse & reverse side should also be disappeared Report this Post to the Staff

chgk1628 Valued Member Hong Kong 155 Posts	Posted 07/24/2023 11:25 am Can you please tell me about your opinion why it's "Wrong" ? The obverse & reverse devices were still clearly observed. Report this Post to the Staff
okiecoiner Pillar of the Community Canada 5595 Posts	Posted 07/24/2023 2:04 pm If you were to drop a coin in acid or even Coke, then it would slowly eat away at all the external surfaces. When something is buried, then you have some deterioration from the inside out, as the actual alloy of the coin is affected. It's a coin withy environmental damage, probably buried for years. There certainly is acid or environmental effects on the surface of the coin, maybe enough to make the wieght difference itself. Report this Post to the Staff
