"Mint masters traveled from place to place, not always in large cities, but also in villages".
After examination, the Troya Museum determined that the coin dates back to the 10th century CE and belongs to the Eastern Roman Empire period.
The coins were found near the foot of a late Roman fortified tower, known as a burgus, which was used for military observation.
"This is an incredible story," said Ulf Dräger, curator of the State Coin Cabinet of Saxony-Anhalt.
The hoard includes coins exclusively from Alexander Jannaeus, who ruled from 104 to 76 BCE.
The hoard includes coins depicting both William the Conqueror and Harold II, offering insight into the turbulent period following the Norman Conquest of England.
The entire collection of coins is part of a coin "treasure" that was hidden in the late 5th or early 4th century BCE in Asia Minor.
"The pendant demonstrates a desire to plug into this vanished age," noted numismatist Adrian Marsden.
