This coin of Constantine II is rated R3 ( Extremely rare). The condition looks fine, but the edge is partially cut. It's listed under RIC VII ANT 87 with Theta as officinae. As such, the listed coin has 2 standards whereas mine has only one. That would be puzzling me all together. I really don't know what I have in hand.
The two-standard types came earlier, one-standard later. They are different coins. I don't know whether your example is rare or not, but you need to look for the one-standard types. Also, it's Constantius II, not Constantine II.
Wildwinds lists the coin attributed RIC VIII ANT 49 with officina Z . Mine has officina Theta. Maybe I'll find officina theta in the RIC books.
RIC clumps all the officinae under one number for these. So it's going to be 49 whether the officina is A or B or Z or whatever.
I believe JA is correct about Constantius rather than Constantinus but there is NO WAY that this is RIC 49 with those dots above the standards making my guess RIC 52 which is a C4 or so common you should have no problem finding more. RIC lists it for all 15 officinae. The certainty about which brother requires you have faith in the spacing of the part of legend lost not being enough for the extra letter or if you think, as I do, that the face is more like Constantius. The 'scarce' Constantine RIC 51 is in the RIC plate making me even more of the opinion the coin is Constantius'. This is my Z RIC 52. I do not have a theta.
