Archaeologists in Turkey have unearthed a hoard of Roman-era silver coins in a jug buried near a stream.

The 651 coins are about 2,100 years old, but despite their age, the text and imagery engraved on them is still legible, said Elif Özer, an archaeologist at Pamukkale University in Turkey who helped excavate the coin jug in Aizanoi, an ancient Greek city in Turkey’s western Kütahya province.
