<p>[QUOTE=&quot;GDJMSP, post: 315922, member: 112&quot;]No it isn&#039;t. Acetone is primarily good for one thing - removing PVC. It can also be used to remove some types of glue, tape or tape residue and just plain old dirt and body oil residue on circulated coins. Other than that it won&#039;t remove anything.</p><p><br /></p><p>When somebody says a coin has been dipped they are referring to a commercial coin dip. There are many different brand names but almost without exception they all contain 1 key ingredient thiurea. It is an acid and it will remove toning and a small, thin layer of metal from the coin. That&#039;s what makes the coin look bright and like brand new. And if the coin is dipped for too long or too many times it will remove luster as well.[/QUOTE]</p><p><br /></p>
