The 1964-D Dime in pics #1 ans #2 appears to be a very good candidate to be an RPM-002. Hard to tell about the 1964-D Dime on pics #3 and #4 due to the wear and dirt. Just remember, if you find that you have a coin that you believe is a Variety (i.e. RPM, Doubled Die or other) and it matches all or most of the Die Markers, then it is likely the Variety. Just because a coin you have and suspect is a Variety has an extra not noted Die Marker, that does not exclude it from being the Variety. It likely means that the coin is of a later Die Stage (State) than the documented and recorded specimens.
