<p>[QUOTE=&quot;Oldhoopster, post: 3173958, member: 84179&quot;]Acetone doesn&#039;t affect toning.&nbsp; It only removes (many) organic compounds that have adhered to the coin.&nbsp; Some of these, such as the plasticizer decomposition residue from PVC flips <u>will</u> damage the coin if not removed.&nbsp; There is a chance that toning/surfaces under the residue may be different than the rest of the coin depending on the amount of time the residue was in place, or if the residue caused damage.&nbsp; Acetone WILL NOT turn the coin dull white, unless that was the original surface under the tape residue.[/QUOTE]</p><p><br /></p>
