In Greece, around 119 coins were found, with an iron lock that could have been used to lock a vessel in a decayed structure at the port of Korinth's ancient city.
But archaeologists are trying to solve it: why did not anyone come to pick up this disaster after it had collapsed?
"This is an excellent question and we are delving into our mind," says classical professor Paul Scotton at Long Beach, California State University, who excavated for the Lechaion Port and Strand Project.
"Sikkeler was found under the collapsed roof of tiles and 30-40 centimeters below today's ground. It's an important question why someone is not turning to it because it's so close to the surface. "

Scotton says his owner does not take it or does not want it, and explains that the answer to it will be just an assumption.
Corinth was an active city for millennia in ancient and medieval times, and today there is a city not far from the ancient city of Korint. Lechaion is the Corinthian port area.

Many of the bronze-made coins were discovered in excavations made in 2016 and 2017; but some of the coins still need to be cleaned. Archaeologists say there are no human remains beside the coins.
Archaeologists have found ruined buildings, along with ruins that could be work areas, where iron slag, untreated iron, fired animal bone, and hardwood residues.
"The earliest coin in the grave was a short period after the death of the Roman Emperor Constantine (ruled between 306-337 BC), the two latest coins belonging to the rule of the Byzantine Emperor Anastasius I (AD 491-518) says classical period professor Michael Ierardi.
Ierardi said that, depending on their weight and size, coins probably date from 491 to 498 and that Anastasius was dated before the Byzantine Empire reformed the printing system.
Research continues on Sikkeler.
