1999 D Lincoln Memorial RIDB

I'm not sure what the last image. My guess if the ear/hair area of the obverse. But this is not PIDT We often see this on the open field areas. Also more on the older style of die creations with the higher profiles. (Multi hub process creation of dies) On the new coins, they are the lower profile devices on the single squeeze dies. The doubled dies on these are different from the older style dies. This is either the dies normal design, or is from die damage like on the Feeder Finger Damaged dies. The struck fingers alter the flatness of the fingers:

Note the distortion on these?


These slide through a designated size opening on the machine. So when they get altered, the damage happens to the dies, and not the machine.


These are often at the same angles depending on the denominations. Some of the struck areas fall off of the fingers and into circulation:


Recently I've been noting that this issue damages a lot of dies and why they are over polished so much just to recuse a die:

Clashes don't create these issues so deep that they get polished that deep. But keeping aware of this now, I'm starting to fill in pieces of the mystery puzzle. (You know the type of Jig Saw puzzle, without any image to go by?) But being aware of this helps us know more about the process.

CoopHome: Why are dies over polished?
