Spitsbergen coinage is interesting - it's issued for a Russian coal mining town off an island that belongs to Norway. All coins were issued in Russia in 1946, 1993 and 1998. I'm missing just three coins. My collection can be found here: http://gxseries.com/numis/spitsbergen/spitsbergen.htm Please feel free to post some of yours.
Very interesting niche you've found there. I like the reverse designs of the later pieces - the various fauna over the island geography. Somebody obviously took some pride in crafting those. Can you imagine working in such an isolated, cold, and desolate location? The pieces are probably uncirculated because nobody wanted to go outside and spend them.
