43 steel split finish penny

This has got to be an fairly rare occurrence isn’t it I’ve tried to look any coin up that I post there and some of them I can’t find that’s the reason I’m asking you guys

Interesting.. I'm not sure

 

My 2 cents. The bottom half appears to have plating bubbles and the devices not as sharp as they should look. So possibly a reconstituted finish that didn´t adhere well and half has fallen off. Just a thought.

 

Almost like a lamination. Note it doesn't involve the rims. We'd need crisper pictures to rule in or rule out out.

 

IMO it is a detached lamination.
Here is a photo with an example from my collection.

 

Looks to me like it’s been replated and has me a piece of tape over part of it.

 

Welcome to Coin Talk.
After looking at it for some time, my conclusion is that it was partially dipped into some chemical or liquid. The line is too perfect and the differences between the upper and lower is just different enough. BUT, then an examination of the reverse, tells me that must be incorrect, so I have to side with you, as a possible lamination. That is one I haven't seen before.
Thanks for posting and let us know if you find a definitive reason for it.

 

Looks like a High School Chemistry project gone bad.

 

Thanks everybody I actually have a quite a few steel pennies that have very odd things wrong with them. The old guy I bought them from know what was wrong with me either he said that’s the reason he had him, but he gave up

 

I actually have spent well I know hundreds of hours looking at coins because in just one batch I went through 55 gallon pails of pennies three times. It seems like there’s so many variations of what things could be nothing is quite as easy as one of my quarters I will post

 

I've been looking at circulation change for 75 years. Very dedicated to coin collecting. I haven't found one coin that I could sell for any interesting amount. If we look at any coin with enough magnification we will find things that look like design variances or errors. They are more appropriately labelled as manufacturing variances.

Understanding the difference between mint errors, minting variances and post mint damage is a real challenge.

It is very difficult to find a coin in circulation that fully complies with the original design criteria.

 

that’s very good information. Thank you. I never thought about it. That way

 

Keep after it and post full size photos. You will get more feedback if the variations are described and easy for old collectors like me to locate on the postings. I hope you find that one that I have looked 75 years for and not found. Good luck.

 

I do have a couple air coins that have never been circulated. Actually, I haven’t even touched them with my fingers

 

Best not to touch a coin with your fingers as they will leave a residue on the coins surface. After a time you will see a fingerprint appear. Fingerprints can not be removed once that occurs.

 

I don't understand what an air coin is. Was that a typo?
