Great story, Don, but there aren't that many people collecting stamps anymore. I don't know anyone who would pay that price for it. 10 years ago it might have been 20 million.
Back in the day,..........stamp and coin shows shared about 50/50 the display/booth space.
Today, I observe that if stamps are even offered, their space is less than 10% of the available space.
To bad, since that was/still is a great way to learn history, especially US history versus learning US history from coins.
