I am quite certain this is from Thessalonica, as I can clearly see the legend, "THESSALONIKEON" However, the patina break on the obverse (reverse?) obliterates most of the text, leaving only a Theta in view. Obv(rev?): Visor(?) bust right. TH--- Rev(obv?): Bare bust right. THESSALONIKEON. 21mm 8.4g The one side has a flat shovel-face typical of Marc Antony, but there's no way.
Well, historically you're close That's Augustus with Divus Julius Caesar. https://rpc.ashmus.ox.ac.uk/coins/1/1554
Woohoo! Thank you, trying to find a coin with nothing but "Thessalonica" and "visor" is really a losing battle. lol
Great coin! Here's mine; Augustus with Divus Julius Caesar (27 BC-14 AD) MACEDON. Thessalonica. Obv: ΘEOΣ. Wreathed head of Julius Caesar right; uncertain c/m on neck. Rev: ΘEΣΣAΛONIKEΩN. Bare head of Augustus right; Δ below. RPC I 1554. Fine. 12.3 g.21 mm. Former: Numismatik Naumann The D has been interpreted as either a denomination mark (four assaria) or, more likely, a date - year four of the Actian era (28/7 BC). The ligate NK monogram has been generally accepted as a reference to Nero (Nerwn Kaisar). This is problematic considering that Thessalonica had abundant coinages issued under Claudius and Nero, such that countermarking these quite older coins would be unlikely. Touratsoglou (p. 105) follows Kraay's suggestion that the NK is an abbreviation for Nike (NiKh), and was applied to the coins during celebrations of the city's 50th anniversary of its grant of liberty by the Romans. All but two of the known specimens of this countermark occur on the coins of this first issue of Thessalonica, and the wear on the countermarks is nearly identical to that of the coins, suggesting that the countermarks could not have been applied very long after the coins entered circulation.
