Roman coins archaeological evidence dating
The Roman coins are not so easy to identify from the obverses alone.
The coin that features most frequently in the news reports appears to be a copper alloy coin of Constantius II (337-361AD), the son of Constantine the Great.
A trove of 2,976 silver Roman coins stamped with emperors and their family members has been unearthed in Sofia, Bulgaria, at an ancient Roman and Thracian city inside the city’s borders.
Archaeologists say the name of the apparent owner of the hoard was inscribed on the clay vessel in which they were stored.
So far the only published images of the finds show the obverse (the “heads” side) of the four Roman coins and of an Ottoman copper mangir coin with a clear Hijra date 1099, which corresponds to 1687 to 1688 in the common era.
Like the Roman coins, the Ottoman coin poses problems, because it was issued after the presumed abandonment of the castle in the 15th century.
Even more significantly, large and identical payments could now be easily made which made possible a whole new scale of commercial activity.The coins were minted over a period of 100 years, says the blog Archaeology in Bulgaria .The earliest coins are of Emperor Vespasian, who ruled from 69 to 79 AD, and the latest are from the reign of Commodus, 177 to 192 AD.Roman coins were first produced in the late 4th century BCE in Italy and continued to be minted for another eight centuries across the empire.Denominations and values more or less constantly changed but certain types such as the sestertii and denarii would persist and come to rank amongst the most famous coins in history.
