You're driving me nuts with those:-) You have some of the best luck I've ever seen. For those of you who want to see what real RPMs look like, memorize those pictures:-)
The pictures exhibit the things we especially look for on RPMs. Plant those images of distinct separations on those mintmarks firmly in your minds and you should always be able to tell the difference between these,
Machine Doubling, split plating, and
Die Deterioration Doubling!
Nice Pictures and very nice coins! Thanks for posting them.

PS: It could be the photo, but the 1958 D looks like it could be a doubled die.
