has Constantine with sideburns and a moustache

I've got a bunch of photos of this issue saved... the bearded/not pattern seems to go by officina.

Officinas B + E were used almost exclusively for Constantine, and have him without beard, which I assume is how he really looked.

Officinas A + G were used primarily for Licinius, as well as A for bearded Maximinus, and have Constantine with beard, maybe because the engravers were too lazy to differentiate.

that's a good observation about the workshop

[Joshmaggosh]

That is an interesting difference. I'll be on the lookout for a A or G officina coin. Here's my beardless B officina coin.

Here's my beardless B officina coin.

Yours also doesn't have the long sideburns...so Constantine is even more clean shaven.
