It's worth pointing out that, with regard to the Apollo 12 cover that started this thread, if we believe the seller's update, then the cover was listed as what they knew it to be.
Before this thread, more than one person knew that Apollo 12 covers with a Bishop cachet that were signed by the crew before launch and postmarked for the launch were insurance covers.
Even now, there are undoubtedly still people out there who know that.
Of course, what those individuals knew/know on the subject was/is incomplete and ultimately inaccurate, but that doesn't change the fact that they knew it.
Knowledge, at its core, is just a belief that you're entirely sure of. What we know isn't necessarily what is. For example, how many people know that astronauts aboard the ISS float because of a lack of gravity? Or that the Coriolis effect causes water in the southern hemisphere to go down the drain "backwards" compared to drains in the northern hemisphere? Or, thanks to the last link and other identical information out there, that drains are too small for the Coriolis effect to have any impact on the water direction? Or any number of other things?
It'd be great if sellers only said what they know about the items they're selling, but that won't cut down on cases like this where there apparently wasn't any malicious intent or necessarily wishful thinking.
