At first glance, it looks like a nice indent strike with partial brockage... but there is so much more happening here... Have fun!!

spru Bedrock of the Community United States 12477 Posts	Posted 05/03/2017 01:29 am I don't like pop quizzes. There is definitely a lot going on and combined striking errors, I believe. I'll leave it to more experienced folk.

Alan Pillar of the Community Canada 1463 Posts	Posted 05/03/2017 10:37 pm I'll say broadstruck, and the indent was caused be by a reverse counter brockage that didn't eject, creating the enlarged reverse and incused design. What ever that would be called. Edited by Alan 05/03/2017 10:45 pm Report this Post to the Staff
darryldarryl Pillar of the Community Canada 2430 Posts	Posted 05/04/2017 05:46 am Please provide a explanation. The reverse seems obvious but I am curious about how the obverse came to be. Is this a regular sized one cent planchet? Looking a little closer it almost looks like the reverse was originally broadstruck before the fun began however the obverse contradicts it somewhat. Hmmm?

SPP-Ottawa Moderator Canada 10473 Posts	Posted 05/04/2017 10:05 am PCGS just called it an indent strike. But I think there was a real mess in the striking chamber.... the lip on the obverse is impressive and slightly concave. I think it was a normal planchet that was originally struck by a mid-to-late cap on the hammer (reverse) die. Then, this coin stuck to the anvil (obverse) die as a cap itself. At the same time, part of the hammer die cap was removed or fell off or was sheared into a football fragment. This coin was then struck again by a partially capped reverse die or through a fragment of a later stage die cap (note the size of the brockage elements in the indent). The collar die mechanism probably failed in there somewhere... Then the whole mess was ejected. That is the best explanation I can think of... maybe Zimmy can provide additional insight...

Zimmy Valued Member United States 462 Posts	Posted 05/06/2017 08:14 am The third party grading services have a tendency to be very generic on their description of brockage errors. I have a clashed cap counter-brockage U.S. Indian Head cent that was simply labeled a brockage error by NGC. Regarding SPP's coin, it does appear that the brockaged area does seem to show more than normal expansion of the detail, maybe caused by being struck through an early stage counter brockage. Can't be a later stage counter brockage since there is significant area between the design and rim, which evidences that their wasn't much expansion of detail as would be seen in a latter stage counter brockage. SPP's coin is obviously broadstruck. There could be more going on but I think it's struck through an early stage counter brockage. I do think that it could just be struck through a normal cent but the expansion seems too much for that. That's the best I can do. Report this Post to the Staff
