Aside from the fact that it is a Denver mint coin, it just looks nothing like a proof.
You obviously have no clue how the minting process works. How do you propose these phantom letters got inside these scratches? Also, please...
Congrats on your new Connecticut! The attribution appears to be correct. There is a new book on Connecticut coppers just out by Randall P....
Most likely just a filled die. There is also a fair amount of circulation damage in the area, if there was just a trace of the P it might be...
1988 Philadelphia quarters do have the P mintmark. I think it started in 1980.
Looks to be a 46-BB, which is a little better variety. I think it is currently listed as an R-5, which is approximately 31-75 known.
There should be enough detail to identify the variety. It sometimes takes a little time though.
If it was struck on a clad dime planchet, wouldn't it look the color of a clad dime? Pretty clearly a cent planchet, just a little underweight....
Photos are adequate, just a normal corroded cent.
As already stated, it is corroded.
I'm really not seeing any sign of that. Some caked on crud, maybe corrosion around the date, I do see.
Some of the state coinage was struck over existing coins instead of new planchets as well. I don't think that is the case here though.
Double struck Connecticut copper. Not really common but these coins were minted using pretty crude technology by todays standards, so oddities do...
I actually got my first around 1972ish? I still have it, a 1788 M67-v New Jersey. I can't remember the exact price but was definitely under $10.
I've got a pretty decent run of type coins, and I was working on New Jersey coppers by die variety but they just get too pricy for anything over...
Definitely stained and discolored, looks like it was in a nasty environment!
Yes, someone damaged it after it left the mint. Looks like another coin was pressed into it.
Thanks, didn't know that!
No, only the Philadelphia mint made proofs back then.
Nope.
