Reverse of the coin... I see a lot of stuff there that probably shouldn’t be. Anyone else? Last pic is of a proof reverse so you can see what the image should be.
I don't see anything either. Providing the original design image was very helpful but even more helpful are circles or arrows indicating the areas you see anomalies!
Spent some time under a fellows' shoe who was skipping about the parking lot.......it's called 'wear' and 'abuse'............
