Hi, I bought this years ago from someone who just had a huge vat of random coins. I don't know if this is something that happened during minting or later. I've never seen another one like it. Any thoughts? Thanks!
To CCF! Unfortunately, it's just Post Strike Damage (it happened after it left the U.S. Mint, so it's not an error coin). It's a heavily damaged coin. It's now considered a cull coin, and has lost pretty much all of its value, except for melt value.
