Here is something to consider. Just why is everyone presuming the Vikings went down to Persia? Just maybe, the Persians took a trip up to Scandanavia and left some coins there. Why give the Vikings credit for travelling everywhere? Of course, if I lived in that crummy cold climate, I would be heading south all the time myself.

It is also possible that coins travel farther than any one person by being traded from merchant to merchant. However, there are good river routes from the eastern and southern Baltic sea shores that lead to the river systems that empty into the Black Sea and the Caspian Sea.
