<p>[QUOTE=&quot;Bob Evancho, post: 7605268, member: 84595&quot;]I would suspect it was a poor gold mix which caused a planchet lamination which fell off before striking and a slightly cracked planchet. Poor gold and silver mixes which lead to laminations are not post mint damage.&nbsp; Another question arises, When did the lamination become detached? If it detached before the strike, would the die have smoothed the surface?&nbsp; What was the striking pressure at the time?&nbsp; It is unfortunate the planchet wasn&#039;t rejected for being defective. As for what appears to be a raised metal, I would suspect it is part of a retained lamination on the surface of the coin in that area.&nbsp; I don&#039;t recommend trying to raise that part and look underneath to see if the planchet continues to laminate.&nbsp; It&#039;s an interesting error on a C mint mark gold coin.[/QUOTE]</p><p><br /></p>
