<p>[QUOTE=&quot;-jeffB, post: 8180767, member: 27832&quot;]I have relatively few coins that are worth more than one of those bottles. You probably submit one coin to NGC with NCS for the cost of one bottle (currently about $80, looks like). Of course, you can conserve a lot of coins with a liter of acetone.</p><p><br /></p><p>I went with the $10 quart of Jasco acetone from Lowes. It&#039;ll do until I get my own spectrophotometer. (Come to think of it, I <i>might</i> have a student model somewhere in the garage... but that would only be for transmission anyway, not reflection.)[/QUOTE]</p><p><br /></p>
