Variant with jewel on the diadem. The same kind of variant observed for Zeno with VICTORIA AVGGG type.
The Ratto reports a solidus of this type with a "reduced" weight of 3.57 grs. The coin is illustrated on plate V, n°180. Since the photos appear to be to scale, the diameter of this coin also appears smaller than that of a normal solidus.
This series differs from the previous one by the presence of the star on the left on the reverse and a normal size bust. As for Zeno, we notice a finer portrait of the first years (397 / 402), while the portraits of the following series will become wider and Theodosius II will look more to the right, even if mixtures exist from 402. There is a wide variety of portrait styles for this series spanning many years.
