Albert Pillar of the Community United States 1913 Posts	Posted 03/30/2022 03:00 am I saw similar bubbles or blisters on a US Dollar coin. It was explained to me at the time that the "blisters" appeared as "bubbles" caused by a separation of metals in the coin from "out-gassing" as a result of applied heat. I'm no expert here, just an offer of something to look into deeper as something similar was found on a coin I had. Report this Post to the Staff

JimmyD Bedrock of the Community Canada 21607 Posts	Posted 03/30/2022 08:40 am This is a silver coin that would have no layers to separate so I don't think heat would cause it to bubble. This is why I suggested Occulated Gas Bubbles. Read it here https://www.coinworld.com/news/prec...html#:~:text Edited by JimmyD 03/30/2022 08:44 am Report this Post to the Staff
