[QUOTE="GDJMSP, post: 7944119, member: 112"]You're right.

But, and this is the point that whopper64 was making, at the same time it must also be understood that [U]additional damage[/U] can be done to the coin by trying to remove verdigris if you do not do it properly ! It is also important to understand that verdigris is not found on only copper coins. Verdigris is also commonly found on silver and gold coins as well. Including those that are .900 fine and higher. And for those reading this, if there are still some who don't get it, think of verdigris like being like sawdust. Sawdust is produced when wood is cut or sanded.
