Celtic Iron Age Sequani Silver Unit Coin from Gaul 80-50 BC

So far with some experts looking... an exact match Is not found. I think it's most likely to be Gaulish coin from the findspot, it's similar to King Togirix types (ABC 100) of the Sequani Tribe.

It appears to be a Roma-type imitation with helmeted head facing left and a globular horse facing left.
