Constantine I PRINCIPI IVVENTVTIS from London

[Victor]

Here's another coin that should be a consular bust with a trabea; but it looks cuirassed.

Yeah, the shoulder ptergues, and shoulder straps (connecting breastplate to backplate) which end before the bottom of the bust are the giveaways, although some of these depictions do seem a bit confused, with decorated shoulder straps looking very similar to the decorated edges of a consular trabea. It doesn't help that what's being worn underneath a consular trabea often appears indistinguishable from a breastplate, when it's probably intended to be a tunic.

I wonder how often these British yokels even saw an emperor in consular garb?! What were they basing the depiction on?!
