RIC VII Constantinople 10

Contributed by George Clegg (biggyg2),  August, 2009

Note from Dane: Coins of officina A are listed twice in 
RIC: once as RIC 10 and again as RIC 21 with the note to 
21 reading "The off. A coins could of course equally well 
belong to the first Providentiae series".
RIC 21 also lists officina Gamma, so to keep the two officinae separate, I am adding this coin as RIC 10.
