In 1957 a European silver coin dating to the eleventh century was discovered at a Native American archaeological site in the state of Maine in the United States. Many people believed the coin had been originally brought to North America by European explorers known as the Norse, who traveled across the Atlantic Ocean and came into contact with Native Americans almost a thousand years ago.
However, some archaeologists believe that the coin is not a genuine piece of historical evidence but a historical fake: they think that the coin was placed at the site recently by someone who wanted to mislead the public. There are three main reasons why some archaeologists believe that the coin is not genuine historical evidence.
Great Distance from Norse Settlements
First, the Native American site in Maine where the coin was discovered is located very far from other sites documenting a Norse presence in North America. Remains of Norse settlements have been discovered in far eastern Canada. The distance between the Maine site and the Norse settlements in Canada is more than a thousand kilometers, suggesting the coin has no real connection with the settlements.
No Other Coins Found
A second problem is that no other coins have been found at the Canadian sites that were inhabited by the Norse. This suggests that the Norse did not bring any silver coins with them to their North American settlements.
No Use for European Coins
Third, the Norse who traveled to North America would have understood that silver coins would most likely be useless to them. Silver coins may have been in wide use in Europe at the time, but the Norse, as experienced explorers, would have known that native North Americans did not recognize silver coins as money.
There is an argument between North American archaeologists about genuity of a coin that discovered in the state of Maine in the United States. Some of these archaeologists believe that this coin is not a genuine piece of historical evidence. But some of them think in an opposite view.
The first explanation is about the great distance from the Norse settlements. The author indicates that there is a long way from the Norse settlements to the Maine site. This length is about one kilometer implies that there is a very low probability that the coin is related to the Norse. In the opposite state, the lecturer explains that the Norse travel around North America. They transferred so many objects, not only the coins. So this coin can belong to the Norse.
Secondly, the author alludes to this fact that there was not another coin in the Maine site. It can be induced that this evidence is not reliable. On the other hand, the lecturer accounts for the travelings of the Norse from Europe to America and vice versa. Therefore, there is a probability that one of these travelers when they were packing, has left or lost a coin there.
Thirdly, the author indicates that the North who traveled to North America did not use the silver coins as currency. Although Europeans use the silver as fiat money, but not the North.
But on the contrary, the lecturer explains that it may the North use the silver coins for their beauty in their neckless or the other jewelries.
