19 RPMs Found in 300 '60-Ds!!

[Rum River Coin]

Last night I searched a couple hundred 1960-D's and came away with 19 RPMs. They range from simple split serif varieties to RPM001. So far, I have attributed 1x001, 1x006, 1x027, 2x031, 4x049, and 1x052. I have several that I am not sure about. One in particular seems like a LDS 056, but I'm not sure. Photo is attached. Your thoughts?
I have attached three more photos, RPMa, RPMb, and RPMc. At first I was thinking that RPMa was an LDS055, but I don't think so. I would call RPMb an 061 with an outside chance of an 068. Finally, RPMc is close to several. In order of plausibility, I would go with 036, 022, then 067. Enjoy!

or maybe a 60D RPM-050..

I don't see the marker on the S in Pluribus, but the T marker in LIBERTY might be there.

#56 sits a little lower in relation the #50 .

Use the bottom of the 9 in the date to judge

It may take a while to attribute all of those. 60 was a big year. Nice finds.

I think that the positioning is closer to the 050 than the 056.
