About the face value of the coin

On this coin we see the denomination value as the letter Β, placed in the field. Letter Β being the second of the alphabet, the coin is worth 2, so it is a two assaria coin. Denomination assarion / assaria was used for the name of bronze coins issued by several towns on the western and northern border of the Black Sea (Tomis, Callatis, Chersones, Tyras, Olbia and plenty more). Here at Tomis were struck coins of 1 assarion, 2, 3, 4 and 5 assaria, bearing as digits Α, Β, Γ, Δ and Ε.
