<p>[QUOTE=&quot;-jeffB, post: 3506276, member: 27832&quot;]I&#039;m afraid that&#039;s corrosion, and the coins will never be the same -- if you remove the &quot;goop&quot;, they&#039;ll be discolored and/or pitted underneath it.</p><p><br /></p><p>Having said that, you <i>may</i> be able to remove it. Soak the coins first in distilled water. If there&#039;s still gunk on them (and there probably will be), try soaking them in acetone or xylene (both available at a hardware store). If there&#039;s still gunk after that (a distinct possibility), there&#039;s a product called Verdi-Care (invented by [USER=17261]@BadThad[/USER], a longtime user here) that&#039;s particularly good for removing verdigris or other corrosion products from copper.[/QUOTE]</p><p><br /></p>
