I picked some Nickel customer rolls from the bank. Among the finds, two MS business strike 1965's, a 39 and 46 Philly both VF30, or so. A 58 D possible RPM, but has a bunch of die deterioration associated. Then there is this one. It is a 2016D with amazing luster! What immediately caught my attention was "what looked like" a die chip in an unusual spot. Die chips are usually associated with or connect to the Devices. This one is in the middle of the field. I grabbed the loupe to do further examination and actually found that it is not a just a die chip, it is actually the result of Die Damage. In this case a Feeder finger is to blame. Upon the setting of a new planchet, a feeder finger scraped the anvil die. I have never seen this type of damage in such an early state. It seems as if the feeder finger only scraped the die once. The usual suspects show much deeper, and more significant. http://www.error-ref.com/?s=feeder+finger+damage The first two picks are of the coin, Very brilliant with a slight golden tone. It has a very rolled over smooth looking luster, than what a later die state would show streaking lines coming from the rim. Here is a different look at the damage, it is above the memorial. It starts at 2:30 and runs across the field through the bottom of the P and E and ends at the rim. The die chip is above the memorial on the right, it looks to have jumped from that point to the top of the dome, then continued the damage to the other side.
Sorry, but I don't see anything that could be construed as an error. And the reverse features Monticello, not any sort of "memorial".
Right about the Monticello, my bad. Is the damage to insignificant? It is raised from the coin especially, between the E and the rim.
If the blemish is truly raised, then it could be an accidental die scratch. There is no way to establish what might have caused it. Your photos are too small, and the resolution too poor, to allow any outside observer to assess the characteristics of the blemish.
I have been thinking about a scope for this particular reason. Yes, it is raised from the coin, but it is very faint. the only thing that catches your eye without magnification is the die chip. Thanks Mike
