Thank you to all for giving me excellent feedback!! That's why I'm here. If acid can make it spongy and through off the sg, then a composition...
Is there a department that I missed?
Started at the physics department, then went to the lab. Not the chemistry department, working with solids not liquids.
Aren't we all.
Good morning. Took the coin to Kent state. SG came out the same...7.7 to 8.1 range. Actual was 7.8. This is the second college I have been to.
Thank you for the blah,blah,blah. Good for a laugh for everyone. Your right it probably is acid dipped. Retiring from the stamping and plating...
You're probably right. Anyway, the density of a zinc penny is 7.2, the density of a copper penny is 8.8, and the density of a steel penny is 7.7....
Please, I don't disrespect your knowledge. It's one of those things that I just want to confirm. I wanted expertise,that's why I came here....
Hello everyone. I want to thank everyone for the feedback. I'm still working on it. What I do know at this time that it is neither copper or...
I'm trying, but still not sold on acid dip.

Here another oddity. Rim height to coin face measures .015in. On standard 72d it measures .016in.
Don't know for sure, but under black light, it looks like there might be additional lettering amongst "we trust". Not sure yet. Also tomorrow I...
I would completely agree with acid if image dimension or rimming wash out.
Been there saw that. Obverse details do not coincide with treatment. It's all around physical dimensions are undersized, but the actual stamping...
If damaged, rimming wouldn't be as defined. Also rim thickness for a common 72d large date is .025in. This measures .024. Not much difference. See...
I have a 50's acid dipped. Completely different.
No. Not acid dipped. Can see the lines on obverse and the reverse is perfect.
Hello everyone. I'm trying to identify the planchet or possibly some info or some thoughts about this penny. It is a 1972 d large date that is...
