Constantius II campgate from Antioch

[Victor]

It looks like this coin is workshop B; which is not listed in RIC...though it might be H- but it sure looks like a B. I will verify when I get it in hand. What is neat, though, is that it has 17 rows on the right side of the doorway and 16 rows on the left; which beats my 15 row Siscia campgate. Also dots in top row and long block over doorway.

Nice oddity I suspect that will be an H with serifs at the top.

[Victor]

Yes, most likely an H; but I will remain hopeful.

[Lech Stępniewski]

On magnified picture I see quite clear "H" with serifs.
