Morning, Anyone seen one of these before? I haven't a clue where to start. It appears to be bronze that's all I can tell at this point. Photos below. As always any help is appreciated.
http://labarum.info/lbr/?sf_refsear...ruler=&sf_mint=Constantinople&sf_denom=Follis A byzantine follis from Constantinopole; see above a filter. Cannot read much on the obverse to pinpoint the identification.
If it's authentic, then it looks like a Byzantine 40 nummus coin, which modern numismatists often call a "follis" coin. Probably from the reign of either Justin I or Justinian I, because the portrait is side facing, and because on the obverse, the inscription starts with "DNI". The "I" is the first letter of the Emperor's name. In Latin, "Justin" is spelled "IVSTINVS", and "Justinian" is spelled "IVSTINIANVS". So, if the coin is authentic, then it was minted between 518 AD and 565 AD. On the reverse, underneath the large "M", it says "CON". Therefore, the coin was minted in Constantinople. The large "M" is the Greek letter for the number 40, because it is a 40 nummus coin.
