This is a really specific example. From Bill Cullen-era Price...There was a contestant in 1960 named Mr. Jones; if you watched the Buzzr reruns diligently, you might remember him as the one who swore and fell out of his chair during one game. I had the chance to meet him a few years before he passed away and it turned out he had some really good fortune with the specific prizes he won. There was a set of furniture that's now prized among collectors, and a set of stemware from a manufacturer so popular that collectors will apparently settle for just buying one glass at a time instead of buying complete sets. Well, he still had his complete set. He had his prizes appraised at some point in the early 2000s and got such enthusiastic feedback from the appraiser that he immediately worked out a deal with an auction house. His cut ended up coming to something like $200,000.
BTW, Mr. Jones had a nice post-retirement life as a film extra and bragged that he had albums full of photos he had taken of the sets he had been on.
"They let you take photos on the set?"
"No, but I'm an old man and I don't know better, okay? If somebody tries to stop me, I act all agitated and scared and they back off, and I go back to taking photos."
