I was going through my coins the other day and found this really ugly coin. I didn't think much of it till I took a little bit closer look. Ya just another old coin left out in the weather all rusty . This coin kind of interested me it felt different . So I took out other 1957d coin out and this coin was thicker ,I thought. So I decided to weight the good coin it was 3.1 g and the ugly one was 2.7 g. That to me was I thought was expectable it rusted the weight away right. But something bugged me what was this shinny spots coming out of the old coin and if this was copper and left out in the elements where was all the green patina ?. Now this kind of bugged me so I took a closer look at the coin with my computer and great camera ,what I found was lot of tiny little beads on on the ugly coin. Some were very shiny some were not. I had to look real close and take some pictures so every one can see .Let me know what you think. I thought this was interesting! Thanks Dan Report this Post to the Staff

NumisRob Bedrock of the Community United Kingdom 17911 Posts	Posted 02/04/2025 2:53 pm Looks to me like it's been in a corrosive environment, maybe soaked in acid or buried in very acidic soil. I've dug up George V halfpennies in similar condition in England. My Trade List: https://goccf.com/t/194596 My Wants List: https://goccf.com/t/191710 Report this Post to the Staff

Marv65 Bedrock of the Community United States 10504 Posts	Posted 02/04/2025 4:19 pm 95% copper cents don't "rust" - so the logical explanation is acid exposure as previously stated. Report this Post to the Staff

Sap Moderator Australia 16816 Posts	Posted 02/04/2025 8:00 pm The OP is correct in that bronze coins normally do turn green when buried in the ground. What I suspect has happened here is that it was indeed buried and was originally was green, and someone has attempted to clean it up a bit. There's clearly some surviving green, lurking in the low points where the cleaning didn't reach. Cleaning would also explain why the highest points of the coin are bright shiny copper. 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
realdeal101 Valued Member United States 113 Posts	Posted 02/04/2025 8:01 pm Thank you everyone this is great .Thank you for your help ! I wonder if there are more samples of this process, it would explain a lot why it doesn't attack the other metal in the coin ,that silver looking bubbles and silver in the rim and the distortion of the letters .?
