I never knew that. See, always learning. I love learning. Thanks for the insights. They must go out to bid. Because the spider man one, which I have 2 of with the actual signature of Stan Lee, was minted by Poland. Interesting tid-bit of info. When he dies, I hope to sell it for some fanatic for 10K. LOL. I have #7 and #9 out of 25.
I do like this 4 series Marvel set. Only 3500 minted for each coin - they broke up the sets, so if someone buys 50 of the Captain America, then they are out 50 sets. I found that to be interesting. If one is more popular than the other, the sets will be diminished. Trick is to find out which of the 4 is most popular and 'attack' that one. That is of course if this series is popular, which I believe it will be. However, no sales just yet.
