Martini notes the letters which he believes to mean TI(tus?) or T(itus) C(aesar) A(ugustus). He notes these issues as struck generally on issues of Augustus. Martini places the issue of these coin types to the period of Vespasian and Titus. It was in the Thrace-Moesia area that these countermarks were applied to circulating worn coinage.
