T-BOP Rest in Peace United States 18456 Posts	Posted 08/29/2019 09:05 am Excuse me for being naïve on this as I'm not an error or variety collector ,but why would the mint repunch a MM in the first place ? Was it done by accident or ? Report this Post to the Staff

John1 Moderator United States 56855 Posts	Posted 08/29/2019 09:19 am Pre 1990 the MM was applied to each working die by hand. If the first attempt was in the wrong place or not set deep enough they would repunch it,hence RPM. John1 Edited by John1 08/29/2019 09:20 am Report this Post to the Staff
stoneman227 Pillar of the Community United States 2376 Posts	Posted 08/29/2019 09:24 am Before 1996 , all dies reqired multiple impressions by the hub to bring the design to completion. The act of each hubing will harden the die so that it had to be softened in between. The mintmark puch had to be used multiple times as well. Because of this , rpm's and certain classes of doubled dies were able to be created. The date John stated is the cut off for rpms. Not the 1996 I stated for dd's Edited by stoneman227 08/29/2019 09:26 am Report this Post to the Staff

Also, the dies may pass from one mint to another and the MM may have been changed, thus the D/S or S/D varieties.
