Watch List notes:

1st century B.C. Æ (12 mm, 1.96 g). Two swastikas with a taurine at each arm / Railing surmounted by a circle from which arise five arrows. Pieper 427. Rare and choice. Olive-green patina. Nice very fine. 

The interesting symbol on reverse is not a tree-in-railing, but a circle on a railing that shoots out five arrows.
