<p>[QUOTE=&quot;SuperDave, post: 2378817, member: 1892&quot;]Acetone is an organic solvent which removes tape residue <b>completely</b> and safely to the coin. I&#039;ll have to re-emphasize the caveat I posted, though - when coins get partially covered with something, the surfaces patinate at different rates. So, if there&#039;s something else also on the coin which the acetone will remove, the surfaces under what it removed might look &quot;cleaner&quot; than the areas which were able to patinate, leaving a coin that looks &quot;cleaned.&quot; </p><p><br /></p><p>Like every form of coin conservation, even something as benign as acetone - <b>every</b> raw coin I buy gets an acetone rinse if it&#039;s appropriate to the caveat, and I advise that same procedure for everyone - must be carefully considered.[/QUOTE]</p><p><br /></p>
