Once you get your eyes into what over polishing of the dies does to the surface of the die, they seem to pop out at you. This one is on a nice mint state 1951 commemorative 5-cent, on the obverse.   That said, I have only found this phenomena on coins that are paired with reverse dies that show Die Deterioration Doubling of the date.

Purelywasted - no, what you are showing is Die Deterioration. You can find additional information on link that John1 posted. John1 - yes, over polishing. The always occur in the fields, off trailing edges of the devices.

Quote: Is this coin copper?  100% pure nickel... it was photographed under low light conditions to highlight the Trail Dies.

I have in my possession a 5 cents 1947 with parallel lines +/- similar on part of the reverse and I wonder what the origin would be. Trail Dies, Tool Damages, or other? Someone has an idea? This is the variety described in Michael K. Blais' catalogue called " 2 Dots (Above the 4)". However, on the other examples of this variety that I have observed, these lines were not present. Note: The reverse has nearly 10 dots on this coin.

ainsivalavie, those are really sharp, like tooling marks on the dies...
