1967 quarter error

[A-new-numi]

On the reverse of this coin, there's a crack that goes east to west, rim to rim. The craziest part is that the crack is cutting off the eagle's head I've never seen this before and I just really enjoy having it. Just trying to figure out the correct numismatic term for it. There's a corresponding "speed bump" (just what it looks like lol) on the obverse. I did read that there's a die variety for this 1967 and the die marks match exactly to what I see. Thank yall

Appears to be Post Mint Damage (PMD) - Some might respond that this is a vice job.

looks like goup to me. would probably come off with acetone or paint remover.

[occnumis2021]

the line across the reverse and the white/yellow stuff below it appears from the images to be something that can be removed as it didn't come from the mint like that.
