Error Or No Error? Any Help Would Be Great!

FYI I'm a total amateur so forgive me if I am unaware of the obvious if this is just a damaged coin at the hands of a human.

I think that's a 2019 P. If it is, it has had a really rough life. In my opinion, it is PMD on this one.

This coin is Post Mint Damage. A mint error on the other hand is defined as a coin made incorrectly at the mint and encompasses anything that happens to the coin up until the final strike of the dies. The difference between an error or post mint damage is found in if the defect on the coin occurred before the final strike of the dies or after. This is a critical thing to determine in order to know if a coin is a mint error or simply PMD and prove the defect on a coin to be pre-strike (and so a mint error) or post-strike damage.

As soon as the last strike occurs on a coin, anything after that is defined as PMD...and even if it happens at the mint, and even in original mint packaging with a number of gouges or other forms of damage on it. While the struck coin is making its way through riddlers, the counting machine, or other processes at the mint after striking, it could be gouged, scraped, stamped by automated machinery (many robots are now used in the mints), or could be scraped or otherwise mutilated. Any of these things, if they occur after the last strike of the dies to the coin, are also still considered PMD. Many coins from that point also can have post mint damage in circulation which is where many of the PMD comes from.

Heres a video that might give you a quick look at post mint damage and errors intended for those just starting out.
