I don’t know what might be the real
mint but I found some indications ; a specimen with this
type was contained in the Colonel Leake's
collection and was acquired by the University of
Cambridge,
Leake, Kings. p. 39. 7 (
Commagene) the description of this coin is found in Imhoof- Blumer, Z.f.N. i (1874) pag.332 n.13, minted under Amyntas (39-25 a.C.)
