Kings of Macedon, Antigonos Gonatas, 277-239 BCE Helmeted head of Athena right B - A (for Basileus Antigonos, I think?). Pan standing right, erecting trophy. Symbols to left and right, monogram beneath Pan. Ref: Sear 6786 I only included one very general reference (from David Sear Greek Coins and Their Values) because the specific type reference can vary, depending on the control symbols and monograms on the reverse (left and right fields and below/between Pan's legs). Yours has a Macedonian helmet for a symbol in the left field (like my first two). Looks like ATI monogram beneath (or similar). There's a monogram to the right, but off your flan, probably a wreath like on my top two (underneath the "A"). Here are some of mine: A whole bunch of examples: https://www.acsearch.info/search.html?term=antigonos+gonata+trophy+ae&category=1
