I think this is a " Stiff Collar Strike " ... Here's some info on this error . http://www.error-ref.com/stiff-collar-strike/
This is quite interesting. I haven't found one of these so I read your link , many thanks ! From what it said the obverse of your coin may well have been the hamer die which is not the orientation of the dies that I thought was used since the mid 90's. Maybe Mr. Diamond will chime in . Excellent find !
I don't have the coin yet, Mike did show on the Coneca forums and here's his comment .. 07-27-2016, 09:05 AM #2 diamond Join Date Jul 2007 Posts 1,968 Correct. Since the vast majority of recent off-center strikes (2002-present) show the effect of a stiff collar, it should probably be called a "stiff collar effect" since it no longer amounts to a separate error. Schuler presses simply have stiff collars as a built-in feature. Mike Diamond. Error coin writer and researcher.
