Note: These light cast asses of the Severan period are noted by Cohen as "cast in Gaul." The material is always brass. They are often of rare types, and the cast brass versions are more common than the originals. At least three others of this particular type, cast from the same original coin, are known; one is in a Forum Ancient Coins gallery here. The use of a single struck original to create many copies, perhaps with a separate clay mould for each copy, is typical of these "cast in Gaul" coins.

As to the weight, one known example of the "thunderbolt" variety of the original type weighs 12.57 grammes, compared with this coin's 5.82 grammes, the 3.49 grammes of the example linked to above, and the 6.6 grammes of another known specimen.
