previous edition of T-Bone Tuesday. That coin was part of the first issue of Antioch; this coin is from the second issue and illustrates the system of dots and Roman numerals used as officina marks at the Antioch mint. Trebonianus Gallus, AD 251-253. Roman debased AR antoninianus, 3.8 g, 21.7 mm, 7 h. Antioch, second officina, second issue, late AD 251 - mid AD 252. Obv: IMP C C VIB TREB GALLVS P F AVG, radiate and cuirassed bust (viewed from back) of Trebonianus Gallus, right; •• below. Rev: VICTORIA AVG, Victory advancing left, holding wreath and palm frond; •• in exergue. Refs: RIC 93; Cohen 126; RCV 9653; Hunter 55. Notes: Examples are known from all officinae. The same reverse type is commonly encountered on coins of Gallus' third issue. This coin illustrates the 2nd issue type of Antioch, characterized by a cuirassed and undraped bust with a fine style portrait, and with officina marks on both obverse and reverse. The first issue also shows Gallus cuirassed but undraped, but with officina marks only on the obverse. The third series features a draped and cuirassed bust of crude style and officina marks on both sides. I discuss this in more detail in a previous edition of T-Bone Tuesday. Don't expect much luster on these coins -- my coin illustrates the severe debasement of the coins from this mint. Gallus's coins of the Antioch mint average only 18.9% silver, whereas those issued in Rome were less debased (30.9%), with the least debased being the unknown branch mint previously believed to have been Mediolanum (37.9% silver) (Pannekeet, Table 3). The "cheap metal alloys from which they were struck fared poorly after going into circulation and fared even worse once buried," making them "range from the eyesore to the barely collectable" (@Suarez, ERIC II, p. 474). Post your coins of T-Bone from Antioch, your favorite Victory reverse types, or anything you feel is relevant! ~~~ Notes Pannekeet, Cornelis GJ.
