My guess (if not PMD bottom right of obv) would be broadstruck with a hugely deteriorated die? Only have one of these meself, can be beautiful coins.
I don't collect large cents but looking at your photos and since this coin has been in the hands of collectors and dealers for many years I believe it to be damaged. If it was a Mint error than I think a dealer would have taken a difficult course of action somewhere in the coins past. It's been out there in many hands for more than 150 years. I'm saying Damaged but wait for collectors of large cents to give their opinion.
I think your coin has Post Mint Damage due to the design (america) being flattened out, and loss of design on the Obverse.
Thanks guys for your opinions. Im still believe its broadstruck. The rim and beads looks not been pressed! Its will be very obvious if been hammerd or pressed! I will weight it and compare with other large cents i have.
From the pictures of the edges, it looks like a tapered planchette. That would explain the lack of detail. Just my opinion.
