The first url is for the 1st issue and the second url is for the 2nd issue, so there could be 500 sets of the first and 160 sets of the second. Of course you would need both sets for completeness. It doesn't help that the $100 first issue has a serial of 1636, makes you wonder where the others are.The price is high,
but for the well heeled revenue collector, it would seem fair to have something that most would not have. You don't know how many more are in the postal museum's possession for later sale. I suspect they got all of the remainders that were not destroyed, so more may show up. I want them, but not at that price. Patience
