hello everyone. I hope you are all staying safe!

I have had this coin for a while and just had it listed as "rim fin". due to the huge fin, it kept puncturing the 2x2 when I put it in a binder so I kept it in the "to do" box. now many years later and with more experience under my belt, I took another look at this coin.

I didn't really notice before that the obverse (opposite of the rim fin) looks much like a blakesley effect with a weakening of the rim and even some dovetailing. from the side (pic 4 and 5) you can see what looks like it could be a second strike or indent strike?

please take a look and let me know what you think this is or what happened.

Thank you.
Rob

Yes, I agree that it's an indent from a second strike; you're 4th and 5th photos show it best.

I have a similar 1963 1c, although with a slightly larger area that was double struck.

the extra metal caused from the misaligned reverse die had to go somewhere...

thank you for the responses. now I see the MAD on the reverse and this makes sense. what I don't understand is the effect on the obverse rim, where it has a weak rim, slight dovetailing in pic 6, and the concave area on the rim in pic 4.

Because the dies are misaligned, it could have been sheared up by the collar die if it _just_ was resting on the lip of the collar die, a mere instant before the hammer die struck. The lack of metal for the anvil die (with it being sheared away by the collar die), would behave just like a small rim clip, and not enough metal to form the rim on the obverse.
