This one won't win any beauty contests, but it is 1957-D RPM-003 (VV and coppercoins, WRPM-001 on Wexler).
The other RPM-003s I have found are all Stage D or Stage E, with the BIE and the die clash left of the "1" in the date and inside the NE corner of the "N" in CENT. This coin does not have the BIE and does not appear to have the die clash markers. The lack of die clash markers (or the MDS scratch NE from 1 o'clock on the "9" noted on coppercoins.com) would appear
to rule out Stage C. That would seem
to narrow it down to Stage A or Stage B.
So . . . what say you all? What stage?
Here are the photos:
First, the mug shots:
Here are the date and mm details:
Here are the "195" of the date. The Stage C die clash marker at 9 o'clock on the "1" and the scratch NE from 1 o'clock on the "9" do not appear to be on this coin.
Here is the Stage A and Stage B marker. The suggestion on Variety Vista is that the strength of the scratch and the distinction between EDS and EMDS separate the two stages is difficult on a battered, circulated coin.
Here is the "N" of CENT, with no apparent Stage C die clash marker.
Here is "BERT" of LIBERTY. The Stage D and later BIE isn't there. The coppercoins.com MDS scratch NE from 3 o'clock on the "R" also doesn't appear to be on this coin.
