I want to express my thanks to @Theodosius for his giveaway and to @lordmarcovan for organizing the contest! I was one of the lucky winners of the contest! This coin arrived in today's mail. Isn't it lovely? Constantine I, AD 307-337. Roman billon centenionalis, 3.39 g, 18.6 mm, 6 h. Thessalonica, AD 326-328. Obv: CONSTAN-TINVS AVG, laureate head, right. Rev: PROVIDEN-TIAE AVGG, Camp gate with two turrets, without doors, with six stone layers; star above. -/•//SMTSΓ. Refs: RIC vii, p. 518, 153; LRBC I, 829; Cohen 454; RCV 16254.
A very nice addition. We are so fortunate that on this forum we have so many generous members. And that @lordmarcovan takes time to help organize and coordinate these events.
