amazing . there were more europeans in n.a. before columbus than indians want to admit.
Roman coins were used by Eskimos before Columbus arrived in the New World. There was trade between local factions, the copper may have found its way to the Mediterrian by a series of transactions, with each party unaware of the provenance of the trade goods he was receiving. It may have passed through dozens of hands and several generations before finding its way to Europe.
loose immigration laws back then.
