I dont get the whole post. If there were a demand for 500 of them they wouldnt dissappear all in one day as the mintage of 100 does. The whole idea of a higher mintage was so people who collect them and have a trip planned 5 months off or so still would be able to get there and play for one if thats how they want to get them.
Someone said that gaming might be requiring mintages of at least 200 per $200 strike, that would help make sure there are enough that people dont feel forced to rush and get them or as Jerry suggested, add another 25 each time they run out of a particular strike.
