Anyone who gets on EBay and types 'QSL card' will find an uncountable number of old cards. Basically, they are in the same category as old books-- dumpster fodder. Some of us have an interest in old cards and will pay the modest fees to prevent them from rotting, like W8JYZ and W7UUU. That's excellent Cards as collections are generally worthless. What should be done is to go through them and find the cards from well known scientists and engineers, and sell those separately. In other words, 'part out the collection'. I have QSL cards from W9GFZ and W8JK framed on my wall. It took some hunting to find them. And I was willing to pay the price. The curator would have done well to have a ham post this OP. I am less sympathetic to those without a ham license.
