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.

Is an over polished die the reason for trail dies?

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.

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...

It was also my hypothesis for the moment, I just found the layout of the lines curious, thinking that there might be something that would explain everything better...
Thanks
