<p>[QUOTE="desertgem, post: 505113, member: 15199"]Jeankay, the key is how to remove the shellac. Any rubbing or trying to chip off pieces will cause scratches. Old time shellac is very soluble in acetone or xylene, and repeated soaking, rising should remove it without any scratches. Many try rubbing along with the acetone and dried shellac particles can be hard enough to scratch soft copper. I look for these coins specifically if the shellac looks original and intact as the surface beneath is usually as it was when shellac was applied. Of course some dealers know this and will reapply shellac to mimic origional.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
