Bulgarian archaeologists have unearthed 40 silver coins during excavations in the second largest city of Plovdiv.

The coins, dating from the 3rd century A.C., have images of a number of Roman Emperors or different Gods.

They are extremely well-preserved, meaning they have not been in circulation, experts say.

The coins were located in an ancient hiding place and were a real treasure for this period with their owner being a very wealthy man, they further explain, adding the hiding place in the floor showed the said owner had intentions to get them back at some point, but was prevented, most likely because he was killed.

Since the beginning of the excavations, over 600 coins have been found at the site. All will be housed in the Plovdiv Archaeology Museum.
