wheatchaser140 Pillar of the Community United States 2368 Posts	Posted 11/28/2013 07:03 am Here it is. The reverse seemed to be free of green stuff entirely. If it is verdegris, will it eventually cover the entire coin? And if it is stored in a 2x2 is it protected from further damage?

NJ Bob Pillar of the Community United States 655 Posts	Posted 11/28/2013 07:44 am Very possibly, but the color seems off. Perhaps it's a result of the photo, its color might be what's off. Have you tried acetone? Report this Post to the Staff

I have not tried acetone. Edited by wheatchaser140 11/28/2013 07:47 am Report this Post to the Staff
sel_69l Bedrock of the Community Australia 21786 Posts	Posted 11/28/2013 07:54 am Looks like this coin has been in the ground for some time. It reminds me of ancient coins which look like this, after an initial cleaning. It is possible to have a wide variation in colour with ancient copper and bronze coins, retrieved from burial. Unfortunately, it does have small bronze disease (verdigris) spots on it. Do a web search on how to passivate this problem. Edited by sel_69l 11/28/2013 07:57 am Report this Post to the Staff

ExoGuy Pillar of the Community United States 4415 Posts	Posted 11/28/2013 11:17 am To my experience, acetone will not much improve this coin, but it will remove some of the surface verdigris and thus help conserve it. Do be sure that the coin is thoroughly dry before putting it in a flip. It appears that the verdigris may have eaten its way below the coin's surface. This would be a good coin to experiment with a thorn to dig away at the verdigris. A thorn won't scratch the coin's surface. Report this Post to the Staff
