1893S Pillar of the Community United States 1554 Posts	Posted 06/25/2012 5:25 pm I need help with the correct way of removing green corrosion on a 1829 Large Cent. Oil? Acetone?...I'm a Silver Dollar guy and use acetone on them sometimes but copper I don't know. Thank you! Report this Post to the Staff

amida17 Pillar of the Community United States 4897 Posts	Posted 06/25/2012 5:30 pm Acetone will not hurt the copper. But if it is verdigris acetone will not remove it. Depending on severityit may be a lost cause... Report this Post to the Staff

vermontensium Moderator United States 16679 Posts	Posted 06/25/2012 6:35 pm Depends on how severe the verdigris is. If it's stable, I would not remove. swcoin.ecrater.com Report this Post to the Staff
1893S Pillar of the Community United States 1554 Posts	Posted 06/25/2012 8:11 pm Can't post a picture as some of you know. It's verdigris/corrossion on the edge with a few minor spots in the field. I remember oldtimers (which I basically am) used to use oil of just about any kind and soak for a month. Olive oil, car oil, etc. oil. Any experience doing this? Otherwise the coin is VF.

BadThad Bedrock of the Community United States 19949 Posts	Posted 06/26/2012 08:32 am Verdigris is not soluble in oil, all it will do is create an oily coin. Every coin is different and will require a specific conservation approach based on the level of the problem. It's not wise for anyone to make suggestions without first seeing the coin.

just carl Bedrock of the Community United States 20753 Posts	Posted 06/26/2012 09:59 am It might be a form of the coin growing. This means you should plant it in the ground and see if a Large Cent tree grows. Just kidding I hope you know. No such thing as a Cent Tree. They are all bushes. On a serious note, as Thad said, not a good idea to mess with if you know nothing about what it could be. You could try numerous things but may well ruin the coin completely.
