" The difference is mainly in the lettering. Thracian mint uses letters of uneven thickness with pronounced serifs and terminal flourishes, producing, in Kraay's words, "a spidery effect".
Also, the reverses of Thracian coins are said to be flat or slightly convex, in contrast to Rome, where the reverses are usually concave.
RIC p. 194: Division of middle bronzes of Domitian as Caesar under Titus between Rome and Thrace can be problematic, since the same obv. legend was used at both mints."But the 'Thrace' mint examples have only the DOMITIAN legend form and their frequent occurrence in the coin trade recently adds weight to the argument for a Balkan origin."
