Rule of Thumb - Insurance vs Market Pricing

[Theoldprofessor]

I assume that price guides are mainly geared toward providing baseline information for buyers. But when selling, I would expect some overhead (auction, shipping fees etc) to be normal. And if I were to sell an entire set, for instance, I would assume that the buyer would want wholesale pricing. So I'm guessing that, in the absence of selling each card individually, I would not realize the full price guide value.

And just to say it, the "what's it worth" question has always annoyed me. My dad taught me that something is only worth what someone will pay for it. And without detailed information, I know that everyone here is trying to provide helpful advice in the dark.

Anyway, thank you!
