I'm not sure what happened here. I mean, the die crack running through the denomination side and chip in the loop of the 5 are easy, but what's up with this tiger's stripes? From one angle they look like adjustment marks, which would not be the case on a coin this late. From another angle you can see that they look like some kind of black bars all over that side. I thought maybe it was struck through something, but what could cause this?
Looks interesting. Can you see if there are actual raised ridges where those stripes meet? I was thinking something like the wood grain effect seen on lincolns, but this seems like something else, maybe a feeder finger issue? Almost certainly done inside of the mint but I have no idea what it is exactly.
Yea the dark lines are incuse and the space between them is normal level (making it appear relief next to the lines). I've never seen this before on a relatively modern coin.
Worn roller that rolled out the strip. It left the ridges on one side and they remained on the planchets. look at the 5 and the field around it. You can see how the field of the die has pretty much flattened the ridges but they remain on the surface of the 5. That tells you that they were on the planchet before striking.
