Interesting seal, Joe. I can't remember having seen a similar example. You can find the seal of
Zeno on
Acsearch, which is quite different in
style, more resembling a
type of
Anastasius.
There are also some problems with the reading of the
monogram as Leo. You would have to assume some damage at the bottom right (where C or E would be). Yet I would
still say that your
attribution is plausible. Hard to say if it's two emperors (
Leo I and II) or an imperial couple, like Leo and
Verina.
