These are coins of Roman emperor Julian II 'the Apostate' who reigned from 360 to 363AD. Contrary to the 'apostate' nickname, the wreathed inscription on the back is kin to the modern 'God save the king' since VOTIS MULTIS is Latin for 'many prayers.' I am not sure, but the Roman numerals associated with VOT and MVLT may be prayer and year counts: 10 prayers for 20 more years of reign. Would that be 200 years total? lol
These come as bronze coins weighing about 3.2 grams and as silver silqua weighing about 2.0 grams.
The bronze in our main photo (upper left) comes from Roma Numismatics in London where it sold for 110 British pounds (about $170 US dollars) during a 2014 auction. The Roma coin is in wonderful condition, with little wear and astounding eye appeal. Most you see do not make as strong an impact:
worn: $40 US dollars approximate catalog value
average circulated: $100
well preserved: $200
The silver version of this coin, the siliqua, is worth more than the bronze coins. The large picture below is a siliqua from highly respected Fritz Rudolf Kunker in Osnabruck, Germany. It sold for 300 euros (about $330 US dollars) during a 2015 auction.
worn: $60 US dollars approximate catalog value
