The attribution to Thessalonica was based on the general similarity with 1554-5, but has been rejected by I. Touratsoglou, Die Münzstätte von Thessaloniki in der römischen Kaiserzeit, p. 43, n. 69; the style is different, as is the die axis. As Touratsoglou has suggested, the piece should perhaps be associated with 5420, in view of the similar legend; the style of the two pieces, however, does not seem identical, and some doubt about the association remains. For a similar family group, see Apamea 2010–2010A. It is not clear if ΘΕ refers to Θεός (if so, why omit the last two letters?), or is part of another word such as an ethnic (hence the original attribution to Thessalonica).
