Help needed - cannot identify this (Greek?) coin [solved]

I got this as part of a small Greek lot. I looked through Numista and Wildwinds ("double crescent", “dots”) but I did not find anything. I saw the obverse “two crescents with dots” pattern on an AR coin from Tarentum, but not on an AE one. I cannot identify the pattern on the reverse.

⌀=19mm, w=3.44g, Bronze

Got an answer on another forum, this seems to be a Janus head from Thessalonica. The reverse image needs to be rotated 180 degrees (two centaurs).
