Note: The reverse type on this coin was described as a beehive by Jurukova, based on a superficial similarity in form, and that description has been followed in reference works since (including Varbanov).

Dragonov, following Michel Amandry, says that the object is a civic fountain like the Meta Sudans in Rome, a type in which water flows from outlets at the top and over the shaped stone, to be collected below. This is an interesting, but unproven, idea, which is at least more likely than the beehive conjecture.

The object also bears a resemblance to the baetyl of the Pergaian Artemis. This interpretation, that the stone is a baetyl, requires the object sometimes visible at the base to be a temple, which presumably would contain the object of worship shown in large scale above it.

See also this coin of Maximinus I from Deultum, which shows the same object without the structure visible below it.
