Over 2,000 silver coins from the 12th century discovered near Kutná Hora
28. 05. 2024
The coins had been buried for roughly 900 years until a woman stumbled upon them while walking across a plowed field. Initially stored in a ceramic vessel, the coins were found scattered both on and below the surface. Experts consider this medieval hoard of denarii from Kutná Hora one of the largest finds of the past decade. Archaeologists and historians will now examine the coins in detail before presenting the treasure to the public.
The coins likely date back to the first quarter of the 12th century – a turbulent period marked by conflicts among members of the Přemyslid dynasty over control of the Prague princely throne. At the time, this collection would have represented an immense amount of money and was possibly intended as war booty or to pay soldiers.
“Unfortunately, we lack precise data on purchasing power from the turn of the 11th to the 12th century, but it was certainly a colossal, unimaginable, and inaccessible amount of money for the average person. Today, we’d compare it to winning a million-dollar jackpot in the lottery,” explains Filip Velímský from the Institute of Archaeology of the Czech Academy of Sciences in Prague.
During their survey with metal detectors, archaeologists marked all the sites where they discovered coins with yellow flags.
What did the coins look like?
The unique find of medieval coins in the region of Kutná Hora consists of more than 2,150 coins, among which experts have so far identified mints from three Přemyslid rulers – King Vratislaus II and Princes Bretislaus II and Bořivoj II (ca 1085–1107).
“The coins were most likely minted at the Prague mint using silver that was imported to the Czech lands at the time,” says Lenka Mazačová, Director of the Czech Museum of Silver in Kutná Hora. The coins were made from a mint alloy containing silver, copper, lead, and trace amounts of other metals. Identifying this specific composition can help trace the origin of the silver used.

When will the treasure be displayed to the public?
The experts commend the woman who discovered the coins for promptly reporting the treasure. This allowed them to arrive without delay and begin their work. The scattered coins were located using metal detectors, and everything was carefully documented. Accurate documentation of the circumstances of the find later on can come in handy when processing the artifacts.
The denarii will undergo both traditional and X-ray imaging as well as spectral analysis to determine their exact material composition. “Museum staff will record all parts of the find into the museum’s collection, ensure each coin is cleaned, perform any necessary restoration work, photograph the coins for publication and promotion, and provide numismatic identification, including compiling a detailed catalog,” Mazačová explains.
The goal is to ultimately make this extraordinary find accessible to the public, with plans to display it as part of the minting exhibition in the Czech Museum of Silver in Kutná Hora. Visitors might be able to peruse the treasure as early as summer 2025.
