Could it have happened at the mint before it entered circulation? Yes. Could it have happened after it left the mint and entered circulation? Yes. Is there any way to tell if it happened before or after it left them mint? No. Could it have happened before or during the minting process, thus making it a mint error? No. Since it happened after the strike it is Post Strike DAMAGE (PSD) whether the cuts happened before or after it left the mint.
In the early years of the silver eagles as the dies would start to become worn and start losing their satin finish they would strike a silver eagle through a disk of emory paper to dress up the finish on the dies. Those coins should have been scrapped but a few of them got out and slabbed with the emory paper still attatched. The slab Paddyman posted appears to be a piece of the emory paper that fell away from the coin and got out.
