Comment

RIC 325 was minted by the 1st officina (exergue/officina mark: PXXT) of the Ticinum mint (PXXT). The XX stands for 20 parts alloy (instead of the more usual XXI for a copper to silver ratio of 20:1). The original RIC text mentions 5 different variations/different bust types (bust types according to Pierre Bastiens grouping of bust types; see illustrated: probvs.net):

1. Radiate, draped, right (A bust, no example on probuscoins, Numista #292673);
2. Radiate, draped and cuirassed, right (A2 bust, example probuscoins #1466, Numista #293429);
3. Radiate, cuirassed, right (B bust, example probuscoins #1877, Numista #293430);
4. Wearing imperial mantle, left, holding sceptre surmounted by eagle in right hand (bust H2, example probuscoins #992, Numista #293431);
5. Radiate, cuirassed, left, holding spear in right hand and shield in left hand, from behind (F8 bust, example probuscoins #4700, Numista #293432).

According to Pink, RIC 325 - with its obverse lettering nr. 1 ('IMP C M AVR PROBVS AVG') combined with 'CONCORD MIL(I)' - is part of the 2nd emission (the year 276) and 3rd emission (277) (Karl Pink, Der Aufbau der römischen Münzprägung in der Kaiserzeit VI/I, Wien, 1949, p. 60-61). According to Pink, the 1st officina used 'CONCORD MIL(I)', in the 3rd emission exclusively with the H2 bust (see Pink: "AZ" for "Adlerzepter" or 'eagle sceptre'). Both probuscoins.fr as probvs.net attribute RIC 325 only to the 3rd emission.
