On this sunny morning I made a sunny picture of this bulky Celtic coin that I bought along with some other Celts from Gaul. On one side is the ubiquitous horse, but on the other side there are three things for want of a better word. Can you help me recognize something in it? Or how to hold it? Or even better: help me identify it? Diameter is 22 mm, weight 9.90g. To aid your vision, I added two different directions for the reverse (or obverse, in any case, the other side).
