I see traces of the copper. It was probably deplated and you are looking at the zinc.
From the looks of the upper right corner the zinc rot has begun.
Welcome to the forums @Inkman77.
How to turn cents into “silver” AND “gold!”

@Inkman77....Welcome aboard.... I agree with the premise @JBK put forth....copper gone...just the zinc core...no numismatic value...Cheers, RickO
It probably spent quite a bit of time buried, deteriorated, was found and was then harshly cleaned. It has no numismatic value.
Plated
It's not de-plated (copper removed) imo.
Agree with @FredWeinberg, it has been plated.
