That's quite a site! Tons of information. The notes they show are issued from private companies, like the United States had at one time. I was suprised to see the United States Coal Company notes, they look a lot like WWII and Prison coupons. I wonder who printed them (I bet it was the same company). I must admit I have learned a lot about Svalbard in reasearching for information on it and plus its coming into the news lately with the World Seed Vault that just opened.
One of the pluses about currency collection is that you learn so much more than just about currency. Over the years I have learned so much about the world and I can only attribute it to collecting.
Thanks for the link.... I'm going to go back and browse some more!
