Always nice to see this one, Steve. The horse and rider are off the charts and then there's that angsty dolphin on the reverse. The way the second dolphin is engraved makes it look less like a symbol and more like an accompanying one making a little leap in the background.

Previously owned but I'll post because of the different style. It was also run over by a train. And of course another bronze.. CALABRIA, Tarentum. 281-209 BC. AE15. Scallop shell / TAPAN right, Taras astride dolphin left, holding kantharos in right hand, cornucopiae in left. Vlasto 1840; BMC 479; SNGCop 1085.
