I think I wouldn’t pay anything.
I’m far from a flipper , investor or anything like that but if it had no resale value, I could just print out a (better) picture of Ruth and collect pictures from the internet.
Not many people pay money for things that have no value...I might not be able to get much for my old socks but they provided the $6 of value when I got them
I’m probably straying from the real point, but my answer remains the same.
A picture on cardboard has to have some value or I wouldn’t pay up for it. May as well buy a fake Goudey on eBay , there are plenty...
In my mind, while it could be different in reality, I could turn my collection back into money. A profit or a loss is yet to be determined, but if I knew it was zero, I probably wouldn’t have paid so much for them...
