Here's a little beauty from my $2 Ripped Rims collection:



The rips are impressive, moreso because usually they're on opposite sides of the coin, not the same side on both faces.
 




But here's what caught my attention:



I'm at a bit of a loss to explain what caused this. It doesn't look like PMD, though other letters are most definitely damaged. Nor does it look like a fill to me.

Thoughts? :dontknow:

Lovely photos Fulvio. What camera and lens did you use? How did you manage the lighting? Cheers

Good pics Fulvio ...... not sure about the lettering, perhaps PMD as there is little/no rim there to protect the lettering?
