Hello! I was going through these coins and writing down who issued it, year, the text etc. but I got stuck.
I have 2 different types, one of them is just this, the one you see below, and for the other one actually I have several of them with the same everything,
I just wasn't able to pinpoint who/when. Anyway, according to rules I believe I can only add 1 coin per post so here it is.
At first I thought it should be John II Komnenos, since there are many AV coins of this exact type,
but when it comes to Billion I couldn't find many even after searching through DOC 4. Christ & Emperor / Virgin combo I mean.
Then I was thinking, Manuel I, after John, also had similar coins and yeah there are some, but still I can't say "yes, definitely this".
Maybe because I am just not *there* yet, I kindly ask for your assistance people~
Extra info: 2,3gr, 4mm thick, 2,7cm.
