This is an interesting coin in that it makes me wonder how you can end up with that big fat rim on the obverse if the coin was struck out of collar? Was this coin being struck when the collar blew out? Average diameter is 20.3mm. 1972 Lincoln Memorial cent mint error - broadstruck   |

This is an odd one.
Is that some minor "finning" on the obverse @ k2-k10 and K8-K9?
That would be odd since the reverse is mostly a proto-rim which seems to confirm the collar wasn't in play.

Thanks! As for what looks a bit like finning, it is a what you see is what you get situation. There is nothing on the edge to suggest what is going on, just that little bit of lightly dented in fin-like area on the rim. I was unable to determine is as anything in particular, but then I am still wondering about that obverse rim in general.

It looks like it was struck on a blank, rather than a planchet. In other words, the blank was never upset.

That makes sense. I can see a coin on a blank looking like this easier than a coin on a planchet. Thanks Mike!

How and why would it be struck on a blank and not a planchet,are they not two different sizes? John1 |

John1, blanks are slightly wider than planchets, and therefore have difficulty fitting into the collar. This makes them more likely to be broadstruck. The clues that this is a blank can be found on both faces. The junction between the unstruck obverse perimeter and the coin's edge is squared-off. This indicates that this is the blank's original upper surface. The unstruck perimeter on the reverse is rounded and slopes slightly downward. This indicates that this is the blank's original lower surface.

Tropicalbats, it's likely that the edge of your coin still retains the blank's original cut-and-tear texture.
