Mysterious Roman Coins Unearthed on Desolate Baltic Island Puzzle Experts

Archaeologists have uncovered a collection of ancient Roman coins on a remote island in the Baltic Sea, leaving experts puzzled about how they ended up so far from the Roman Empire's borders. The coins, believed to be from the late Roman Republic or early Empire period, were found during a routine excavation on the island's coastline. This discovery has raised questions about ancient trade routes and the extent of the Roman Empire's influence on distant regions.


In a baffling discovery, two Roman-era silver coins have been uncovered on a desolate, uninhabited island situated in the Baltic Sea between Sweden and Estonia, leaving archaeologists perplexed as to how they arrived there.

A Conundrum Without Concrete Answers

The enigmatic find has left investigators with only conjecture, as the coins could have been deposited by Norse traders seeking shelter, lost in a shipwreck, or even transported by a Roman ship venturing to the distant north.

Ancient Denarii: Timeless Currency Unearthed

According to Live Science, the two silver denarii – Roman currency minted during the reigns of Emperors Trajan (AD 98-117) and Antoninus Pius (AD 138-161) – weighed less than an eighth of an ounce (4 grams) each and were worth approximately a day’s wages for a worker at the time. The denarius, the standard Roman coin, endures today in several Latin languages as the term for “money.” During the late Roman Republic and early Empire, one denarius was equivalent to a day’s wages for an unskilled laborer. However, depending on whether we compare it to minimum wage or purchasing power parity, its value could be estimated to be somewhere between $10 and $100.


Norse Traders, Shipwrecks, or Roman Voyagers?

Archaeologist Jonas Rönnby posits that the long-lasting value of the silver in these coins might have led Norse traders to bring them to Gotska Sandön while seeking refuge from storms. Alternatively, survivors of shipwrecks in the treacherous waters surrounding the island could have carried the coins, or Romans themselves may have brought them, despite no written records of Roman expeditions to the Baltic.

Connections to Larger Islands and Unresolved Mysteries

Similar finds have been made on the nearby, larger island of Gotland, but the discovery on the barren Gotska Sandön is more unexpected. The island, once home to 19th-century lighthouse keepers and a popular spot for pirates and shipwrecks, remains uninhabited today. Daniel Langhammer, an archaeologist overseeing the island’s cultural heritage, remarks that the mystery of the coins’ presence may never be unraveled.

Unraveling the Island’s Enigmatic History


Researchers, including osteologist Sabine Sten from Uppsala University, plan to revisit the island’s shores in late 2023 in hopes of gradually uncovering the site’s intriguing history.
