Incredibly jealous of your catch, @TIF! The figure on the obverse of my Hippostratos square unit bears a passing resemblance to your anguipede monster, but it's apparently merely a triton. The mystery here may be why a marine deity would feature on the coinage of a landlocked kingdom. BAKTRIA, Indo-Greek Kingdom. Hippostratos. AE Square Octuple Unit. 19.36g, 28.5 x 27.2mm. Uncertain mint in eastern Gandhara or the western Punjab, circa 65-55 BC. Bopearachchi 12A. HGC 12, 456. O: ΒΑΣΙΛΕΩΣ - ΣΩΤΗΡΟΣ – ΙΠΠΟΣΤΡΑΤΟΥ, Triton facing, holding dolphin in his right hand and rudder in his left. R: 'Maharajasa tratarasa Hipusratasa' (in Karoshti), Tyche standing front, head to left, holding lotus flower in her right hand and palm frond in her left; to left, monogram. As for anguipedes, how about two in a temple pediment? TITUS AR Cistophorus. 10.77g, 26.5mm. Rome mint (for circulation in Asia), AD 80-81. RIC II.1 515; RPC II 860. O: IMP TITVS CAES VESPASIAN AVG P M; laureate head right.

The chicken / snake legged deity is Abraxas (though technically Abrasax, as it's been mis-translated over the centuries). He is a deity (represents balance, in that it is neither good nor bad, but just "is") in some sects of Gnosticism, which is an early version of Christianity before it became an orthodoxy via the council of Nicaea. Gnosticism sects would be "eradicated" by the Catholic church not too long after, though their texts have popped up over the years. I've been studying Gnosticism for over 4 years now. The attributes of the deity is not to be taken literal, but rather metaphorically as each part represents different aspects.
Beautiful one @TIF ! I was in about the same position as you when I bought my first Bosporan stater : I knew I wanted one but hadn't taken time to study them when that one popped up at auction Bosporan kingdom – El stater, dated 491 (194-195 CE) BACIΛΕωC CAVPOMATOV (anticlockwise).
