I just acquired these two Byzantine Bronze coins which I believe to be Decanummiums of Justinian I (527-65CE). The first measures 22mm and weighs 3.88 grams. the Second measures 19mm and weighs 3 grams.
The first features the emperor standing on the obverse and a large "I" on the reverse with stars to the left and the right. While the mint mark "CON" is quite clear, I do not see a listing on wildwinds for this obverse paired with this reverse containing the "CON" mintmark.
The Second features a bust of the emperor right with a similar reverse to that of coin number 1. The reverse has a large "I" but it has "ANNO" to the left and the date in roman numerals to the right. I am having trouble reading the mintmark and finding a match on wildwinds. Any help with these two would be appreciated!
