Just looks like it was struck using a die that was well into the end of it's life. The flow lines in the die were worn very deep by the time this coin was struck.
The deterioration can take on different looks. There are some with small parallel lines or striations emanating outward toward the rim; there are those like yours with humpity-bumpity marks all over, and then there are also those with the "orange peel" effect that is all pimpley-dimpley. Chris
Humpity-bumpity and pimpley-dimpley.......... If you ever use those terms on FleaBay, don't tell anyone where you got them. Chris
