I have a votive of Constantine I from Thessalonica: AE19 Thessalonica mint, A.D. 324 Obv: CONSTAN-TINVS Rev: D N CONSTANTINI MAX AVG - Laurel wreath around VOT/XX in 2 lines TSEVI in exergue 19 mm, 2.9 g In the mint mark, TSEVI, the TS stands for Thessalonica, E is the officina. Does anyone know what VI represents?
Probably Constantine’s 6th time as consul. There is also TS VII https://www.tesorillo.com/aes/_cec/cecas1.htm
That would make sense. Yet, as you noted, there is a small group of coins with TS_VII mint marks that, according to RIC, were minted in 320. Do you think the VII is just an engraver's error?
the theory that VI means Constantine's six consulship, is a good one; but it is just a theory. The first problem is that there is also a TSAVII issued after the TSAVI, which makes sense numerically; but then it goes back to TSAVI...so maybe just an error. The bigger problem with VI meaning his consulship is that TSAVI was in use for four years.
