Quote:The rim appears to be a wide collar issue...what else is going on (break, chipped,
Cud, retained, etc) I don't know enough to determine but I am hoping someone is an expert in collar errors...
I won't try to speculate without a full straight on clear image of the obverse and reverse.
As already mentioned false rims are commonly seen in conjunction with a misaligned die(s). That said it is also known to show with a wide collar issue.
Got a caliper handy? Thanks, Doug.
