Archaeologists are regulate but excited by the discovery of two silver coin from the Roman Empire on a distant island in the Baltic Sea , halfway between Sweden and Estonia .
No clues break how the coin acquire there , but they may have been left by Norse traders , lost in a shipwreck or brought there on a Roman ship that sail to the far north .
The coin on the left is a silver denarius minted in the reign of Antonius Pius, from A.D. 138 to 161. The emperor’s head and some Latin characters can just be seen.The coin on the right is a silver denarius minted in the reign of Trajan, from A.D. 98 to 117. It shows the emperor’s head and part of a Latin inscription.
Johan Rönnby , an archaeologist at Södertörn University in Stockholm , was part of the team that found the coin with metallic element detector in March , at a beach site check by old fireplaces on the island of Gotska Sandön .
" We were so felicitous , " he told Live Science . " We have this site , but we do n’t know what it is . But now that we have the coins there , it makes it even more interesting to continue to excavate it . "
Roman coins
The two Ag coins observe on the island are both Romanist " denarii"—one from the reign of the emperor Trajan , between A.D. 98 and 117 , and the other from the reign of the emperor Antoninus Pius , between A.D. 138 and 161 .
They each librate less than an one-eighth of an snow leopard ( 4 grams ) and would have represent about a day ’s remuneration for a labourer when they were mint .
Denarii were the standard coin of ancient Rome , and their name survives today in the password for " money " in several Latin - based languages , such as " denaro " in Italian and " moolah " in Spanish .
Gotska Sandön, or “Sand Island,” is one of the most remote islands in the Baltic Sea. The coins were found at a site on the plateau above the modern beach.
Rönnby order coins from the Roman Empire could have remain in circulation for a tenacious time , because the silver they contained always stay valuable ; and they might have been brought to Gotska Sandön by Norse traders who had taken tax shelter there from storms at ocean .

But it ’s also potential they were carry there by survivors from a shipwreck : The water supply around the island are notoriously grave , and the area is littered with wreck , he say .
Another theory is that the coins were lead to Gotska Sandön by Romans on a Roman ship , though no criminal record of such a ocean trip into the Baltic exist .
" It ’s not likely to be a Romanist ship , " Rönnby said . " But you have to consider also that the Romans were sailing up to Scotland and so on , and that there were Romanist generator at that time writing about the Baltic area . "
Baltic island
papist coins have also been found on the larger island of Gotland about 25 miles ( 40 kilometers ) to the Confederacy , but that was perhaps to be expected because it was the location of several towns . Gotska Sandön , however , has no townsfolk or villages .
Gotska Sandön — meaning " Sand Island " — is uninhabited today but was house to lighthouse keepers in the 19th one C . Before that it was make out as a blank space of shipwrecks and as a haunt for plagiarizer , Rönnby said .
ArchaeologistDaniel Langhammer , who oversees ethnical heritage on Gotska Sandön for Gotland County , told Live Science that the young encounter echoed claims by a nineteenth - century lighthouse keeper that he ’d found a Roman coin on the island .
But the mystery of how the coin arrived might never be solve , he said . " We just do n’t know how they get there . "
The distant island was also once frequented by seal hunters — seal hunting is now forestall , but the seal are still there — and by fishers during the summertime calendar month , he allege .
Rönnby and his colleagues , including Sabine Sten , an osteologist at Uppsala University , will return to the site afterward this year . They hope finally to reconstruct the account of the remote island .
