1961-D I'm Seeing Double

OK, last one until I give you people a 3 day break. I open rolls, look at coins with 20X large loop. One pile gets put in the look under the microscope pile; then each of those gets looked at: then if I think it's worth it you get a look. You see less than 2 coins per roll, sometimes none.
This coin is from the same roll as 1961DCUD? topic. 2nd to the last photo has die chip in the same "A" on reverse. Last photo, is that a Cud on top of "N" or just part of the die crack?
Obverse shows doubling as I usually see in my 1800's coins.
Might have thought die chip on top of mint mark was RPM but with the microscope just looks like a die chip. Nice red cent with a lot of eye appeal and no spots. Probably keep this one.
