Although the text on the coin is legible, I cannot assign the officinae mark. It's an ae4, minted in Antiochia. obv: DNIULIANU-SNOBCAES, rev: SPESREI-PUBLICE 1.96 gr , 16.40 mm. mm:AN"N" LRBC: 2639 ( gives only letter A ) What is the officinae? All help and suggestions are welcome. Please feel free to show your coins with legible but unknown mintmark. Have a nice Easter!
RIC lists 15 officina, including gamma I, tentatively listed for Julian, so I think your gamma just has the horizontal bar off the horizontal making it look like an N
I must admit that I only looked in LRBC, I have now checked RIC, with your explanation I see it too! Now I can correctly describe the coin. Thank you!
