Antoninianus - Probus Draped, right; P M TR P COS P P

The original RIC text lists RIC 607 mistakenly as minted by the Siscia mint, while in fact it was minted by the Rome mint, by the 1st (XXIA), 2nd (XXIB), 3rd (XXIΓ), 4th (XXIΔ) and 5th (XXIЄ) officina. See Guillemain (*) #60-69 and Pink (**), p. 55. RIC lists four bust types (bust types according to Pierre Bastiens grouping of bust types; see illustrated: probvs.net):

1. Radiate, draped, right (A bust, Guillemain #66 (XXIΔ), probuscoins -, Numista #292963;
2. Radiate, draped and cuirassed, right (A2 bust, Guillemain #61 (XXIB), #63 (XXIΓ), #65 (XXIΔ), #69 (XXIЄ), example: probuscoins #3256, Numista #293601);
3. Radiate, cuirassed, right (B bust, Guillemain #60 (XXIB), 62 (XXIΓ), 64 (XXIΔ), 67 (XXIЄ), example: probuscoins #3769, Numista #293602);
4. Helmeted, radiate, cuirassed, left, holding spear in right hand and shield in left hand (E1 bust, Guillemain -, probuscoins -, Numista #293603).

According to both Pink and Guillemain, RIC 607 was minted in the year 277, according to Pink as part of the 1th emission and according to Guillemain as part of the 1st series of the 2nd phase.

The officina's of Rome did not use the exergue/officina mark 'KAT' or 'XXIT', which therefore are mistakenly listed by RIC.

There are also two known variants that are in fact minted by the Siscia mint (exergue/officina mark: -/-//XXIQ):

1. [var] Radiate, cuirassed, left, holding spear in right hand and shield in left hand, from behind (F8 bust, Guillemain -, example: probuscoins #1400, not in Numista);
2. [var] Radiate, wearing imperial mantle, left, holding sceptre surmounted by eagle in right hand (bust H2, Guillemain -, example: probuscoins #1417, Numista not in Numista).
