I can't seem to find out what exactly this is. I figure it is worthless, but since I keep finding these in a new dime box, I want to keep one and label it for reference later on. The lines are so thin that I cannot tell if they are incuse or raised, but because they are brand spanking new, they stick out like a sore thumb. My research leads me to believe that these are die scrapes which would make them raised and I am actually seeing it progress (if progression is possible). Here is the worst one I have found so far: and here is one where it is minimal:
Whatever it is, it doesn’t go up on to the relief, so that means either: It’s some weird form of PMD that somehow avoids the design while damaging the fields. This seems anywhere from highly unlikely to impossible. It’s a defect on the die. Or, the coin is struck on a scratched planchet. I think it’s unlikely that a die defect would “progress” from thin, perfectly straight lines to more prominent, yet still perfectly straight lines. That leads me to believe it’s probably a case of some scratched planchets. You can tell definitively by whether the lines are incuse (indicating a scratched planchet), or in relief (indicating a die defect).
They are so light and thin that I can't using loupe But based on the pictures and the direction of the light (10 and 2), I believe they are raised because of the way the light is bouncing off of them. This still fits my original theory that it is the die. All 10 or so I have found have been focused at the center between the torch and branches aside from a couple of small lines going past the branch like in the first picture.
Or possibly feeder finger damage. Regardless, as @paddyman98 said, it's minor and doesn't carry a premium.
Ah, cool! I didn’t think of feeder fingers damaging the die. That may very well be what it is, because it explains the progression without assuming a series of scratched planchets that somehow got struck in exactly the same orientation.
If you don’t believe @paddyman98 you might as well give up coin collecting. This man knows his errors! Reed
