Just got this Licinius II coin. The ebay seller Savoca did not mention the symbol in reverse field. I assume it was missed my some and I got it for $19. I bought two other coins from Savoca so I split the shipping cost which brings the cost of this coin to about $26. Though it's a little rough, not a bad buy. Once in a while I find a bargain.
Licinius II, Victory on globe/vot xx banner, captives, Chi-Iota in left field, an unknown symbol or perhaps a stylized Chi-Rho. Thessalonica mint, 2.17g 19mm, some silvering. Not in RIC and I think rare.
