[QUOTE="GDJMSP, post: 1311983, member: 112"]In a nutshell - improper storage. The green could be a couple of things. It might be PVC residue from PVC flips. Pretty much ever dealer there is sells his coins, tokens, and medals to you with it in a PVC flip. So if you don't take that flip and throw it away as soon as you get home and put the coin in a good coin holder - then you have screwed up. It could also be verdigris. Verdigris caused by a combination of things - impurities in the air and moisture in the air (humidity). So if you don't store your coins properly to limit air contact and humidity - then you have screwed up. Proper storage alleviates both PVC damage and verdigris. Thus the nutshell answer to your question.[/QUOTE]
