NOT IN RIC
UNLISTED ISSUE RIC lists similar issue [ROMA 241], but with m.m. RP-Q (p. 381). However, in footnote 3 Sutherland mentions that: "The A.N.S. possesses this variety with rev. VOT/X/FEL/B" (p. 381). At present, officinae Α, Β, Γ and Δ are attested. This proves that the issue in question should be attributed to Ostia, because Ostia was the only Maxentian mint which for some time used Greek letters for officina letter [OSTIA 14-22]. Note that specimen from officina Γ is listed in RIC as AQUILEIA 128 (p. 326); see also CORRIGENDA, VOL. VI, p. 326. Listed in Drost (Ostia no. 28b). Coin should be listed after OSTIA 22.
