Dictionary of Ancient Roman Coins prefers the term "quasi-autonomous," and I've also seen the term "colonial civic" used. Anonymous colonial civic issue, AE 23, 251 - 260 AD (Trebonianus Gallus to Valerian I), Troas, Alexandria Troas Mint. Obv. Draped bust of Tyche right, wearing mural crown, vexillum inscribed CO AV over right shoulder, CO ALEX TR / Rev. Horse (of Erichthonius?)* grazing to right, COL AVG, TROAD in exergue. RPC IX Online 505 (see https://rpc.ashmus.ox.ac.uk/coins/9/505); Bellinger A486 [Alfred A. Bellinger, Troy, The Coins (Princeton 1961)]; BMC 17 Troas, 46 var. [diff. legends]; see also id. 45, 47-50 var. [Warwick Wroth, A Catalog of the Greek Coins in the British Museum, Vol. 17, Troas, Aeolis, and Lesbos (London 1894)]; SNG Copenhagen 108-113 [Sylloge Nummorum Graecorum, Copenhagen, The Royal Collection of Coins and Medals, Danish National Museum, Part 20, Troas (1945)]. 23 mm., 5.80 g. Ex: Pars Coins; Ex: Kenneth W. Dorney. * See BMC 17 Troas at xviii, citing Cavedoni (Spicil., p. 151) for the suggestion that the grazing horse, first depicted on the coins of Alexandria Troas ca. 300 BCE, is one of the horses of Erichthonius, father of Tros, after whom Troas was named. (Thanks to @Roman Collector for giving me a clue as to the identity of the horse, in this old thread: https://www.cointalk.com/threads/th...oins-of-alexandria-troas.351717/#post-3937346 .) The legends on coins like this vary widely in minor ways; the legends on RPC IX 505 happen to match the ones on my coin exactly (see link above): (The dies are also similar to the ones used for my coin, but I don't think they're an exact match.) If you like, please post your Roman Provincial anonymous pseudo-autonomous quasi-autonomous colonial civic coins, wherever they're from, and/or your coins of any type from Alexandria Troas.
