Thanks. I've annotated my catalog with the Bellinger numbers. The one you indicated as unlisted with the retrograde P, I have annotated as Le Rider #24.
No, that isn't it. Numismatic Studies is a different ANS series of stand-alone single topic works. Museum Notes is a journal containing articles on various numismatic topics, the predecessor to the ANS' current journal American Journal of Numismatics. The Drama Hoard report in Museum Notes XI, 1964, is a section of Bellinger's more extensive article "Philippi in Macedonia." I consulted the dead tree version of Museum Notes XI. I'm confident TIF has accurately reported that the entirety of Museum Notes XI is available on-line, but honestly, Ive never had occasion to look for it and don't have a link. Edit: Ah, I see you found it. I should've kept reading!
