Looks like it was dipped in acid.
The line across the obverse like it was a potential lamination.

 

If it was dipped in acid would it change the weight to 2.90 g. I'm new at this so I don't have much knowledge

 

Looks like it was whizzed/cleaned with an electric wire brush.
It causes dents/pitting and waves in the metal.

 

It could drop the weight.
Not sure if whizzing does the same, but it does give that crazy wavy pattern.

 

Its not like that though. I'll upload another picture using the flash and see if it shows more clearly

 

This is with the flash

 

The surfaces are corroded. I'm guessing acid, but there is a chance it could be mechanical. The surfaces are rough and the details are mushy, and it is not the appearance of die deterioration.

Also, the weight tolerance of a copper cent is 2.98 - 3.24 gms, so you're only 0.08 gms light, which could easily be removed by acid.

 

Much appreciated. I'm new to this but have to start somewhere. I'm glad I started here. I appreciate your opinion it does make sense to me. It's still neat though Lol. Any ideas on what appears to be across his bust? Almost looks like it has letters but can't make it out for sure.

 

Also, what does it mean if it were mechanical? Would it be a mint error? Would you send it to someone to be graded and looked at? I see you are a member of ANA for long time. Stupid question but what is ANA? Sorry

 

Across his bust is what looks like a lamination, like I said originally.

Here is an example I own:

 

Interesting coin @Superloop, thanks for posting.
As mentioned above, ED, Environmental Damage. Doesn't matter how it happened, buried, given an acid bath, urinal coin, it's a damaged cent, not an error and NAV, No Added Value. Worth 1¢.
As for the obverse, it does appear to be a lamination (or delamination to be correct) and kind of cool, but in the coins current condition, probably not worth a premium to a collector.
Sunday, you are coming up on your 1 year membershiphere at CT. Congratulations for hanging in there. LOL

 

Thanks!!!

 

Your coin has a lamination going across it, and it's a nice one. Both coins, his and yours, were smoking away in a strong acid. Hydrochloric or sulfuric cause that look.

 

.
The coin I posted (1955-D) as an example of the reverse of the OP's coin has NOT been subjected to any type of acid. It has been whizzed with an electric wire wheel brush. Similar to the one pictured.

 

Interesting. Learned something new. I agree with you.

 

Sorry, it's acid, we got a lot like these.

 

Please show some photos.

 

I can dig one up if you really need it. Are you sure?

 

Here's one. Hope it holds you, I'm not going through any more just for this...
