1934-D-1MM-005?

The scratches over the date are there and the die gouge above the E is faint. Having a hard time with pictures. Perhaps LDS?

Looks like a match. The upper part of the mint mark shows the RPM in the center of the loop. That is all I can match with the CONECA E-Disk. But all looks correct for location and separation. Nice find.

EI8 a 10x or 20x should show it, I find it easier with a lighted loupe and then look for the markers from sites like coppercoins.com of which most you can see with no magnification. When I started a few months ago I couldn't find anything, just kept looking, asking, etc. At first I could only find the more pronounced ones. I just found my 500th rpm 2 weeks ago and I am still learning. And I cant find a DDR no matter how many I look at even with example coins. Just trail error and time...
