That's a very nice collection theme. It's amazing that even with the latitude such a collection presents some countries are so very hard to find. Best of luck with your continued efforts. Can't wait to see your pics.
I have never seen these before. Can you show us a "tall" stack photo when you get a chance. As always, you have a wonderful collection and I thank you for sharing it with us.
I got my 2011 US Mint Proof set in the mail this morning. It is absolutely beautiful. I especially like the National Park Quarters. Great designs that translate very nicely to coin format.
