<p>[QUOTE=&quot;Dynoking, post: 8314000, member: 81795&quot;]That is not a given. More than one member here have experienced a straight graded coin returned with a details grade after conservation by NGC.</p><p>Conservation can be a crap shoot no matter what the skill level of the person performing it is. Often times surface issues are hidden under the toning.</p><p>If I had that coin I would crack it out and give an overnight soak in acetone. Roll a acetone saturated Qtip gently across the surfaces then follow up with another overnight acetone bath.&nbsp; Repeat with the Qtip. If no more gunk comes off stop.</p><p>At this point a judgment has to be made. Should you continue with a different method or leave it alone.</p><p>I don’t think a dip is appropriate for this coin.&nbsp; The most I would after acetone is Conserv solvent. It will not remove toning or change the surface of the coin.[/QUOTE]</p><p><br /></p>
