I think that I have one of these, but I am unable to make sense of the 'Type Reference'. Can anyone 'walk' me through it please? Below is my coin.
RPC online has a page listing the full references cited in their abbreviations: http://rpc.ashmus.ox.ac.uk/abbreviations/ For the coin and screencap you showed, "S Suppl." = EA Sydenham, The Coinage of Caesarea in Cappadocia (1933), reprinted with a Supplement by AG Malloy (1978), so in that reference, the coin is listed as 338c, with "corr." indicating that there was a correction to the initial attribution (probably corrected in the Malloy supplement).
Thanks T.I.F. I have had a bit of a 'play' and I think that I am getting more familiar with it. Thank-you, again. I appreciate you passing your knowledge on.
The number of works on that list should give a clue as to why we need the RPC online or in book form. As a spectator, I can hardly wait to see the proposed volume V on Septimius but it won't be ready until I'm too old to see, too poor to afford and too weak to lift what will be a massive book. If it ever is completed, the full set RPC will make RIC look like a set of pamphlets.
