<p>[QUOTE="desertgem, post: 799625, member: 15199"]A Re Punched Mintmark occurs when the mm was punched once on the working die, and then as it was to be punched deeper, the die setter moved the punch, so instead of one single mm, it had 2 or even sometimes 3 visible. Then if the setter didn't notice ( or care) that the mistake was made, the die would be inserted into the press and many , many coins , all with the RPM would be made. Some have said that if it was noticed by a supervisor, the die could be withdrawn and corrected, so there are some common RPMs and some scarce RPMs, but they would be a variety. As to whether there was ever just 1 coin made with the RPM would it be an error rather than a variety, I don't know, as I am sure semantics would jump in there. I have never heard or read of such a case though. IMO.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
