The people of ancient Thessaly probably had some difficulties distinguishing between the various bronze denominations of their local coinage during the imperial period. To help simplify matters, the mint not only clearly inscribed the denomination in a central area of the reverse - the numeral Γ (= 3 Assaria) below the horses - but the coin also depicts Nike driving a triga instead of the more common quadriga or biga, which would have helped to distinguish it from the 4- and 2-Assaria pieces that were of similar size.
