me again, going through 6k pennies your bound to find some odd ones.. this one is very thin, a strange yellowish color, and has a smaller circumference than a normal penny. i can't figure out what it is though.
how would that change the circumference though? and keep it's details after enough force to smash it that thin
My guess is that you are going to need a picture of the reverse before this can be steeled. From what I can make out here, I am going to guess that they has a bad planchet.
It looks more like a smaller planchet than acid reduction. I have a couple acid treated coins, but the planchets aren't tapered.
They also don't have nearly half the coin with good detail and half almost nonexistent, some of the coin with a rim and most without a rim.
I've come across a few of these kind of cents but I think it is the planchet defect? I usually use them as change anyways as I don't think it is anything rare. Probably Jim would know.
Maybe, but the area looks recessed, like a de-lamination. Sometimes it's hard to tell if something is stickin up or down.
Haha, okay... I was like, WTF is he talking about? I'm gonna say planchet error too, pretty cool one at that.
It appears to have started out as a genuine error cent, with a cud and perhaps a taper. Unfortunately, someone dipped it in acid afterward, rendering it worthless.
