Well, the 3 tough ones (Toadal, Cheapios, Weakies) are worth about $250 each? A a set of regular folded posters is, what, $1000? So this is probably $1000 too high.
Posters are getting harder to find, but I think the demand for them is also very low these days.
It's been a while since I purchased the tough 3, but I think maybe $200 each instead of $250? The Cheapios has a tape stain, so maybe it's worth even less.
As far as the set of 24, I think maybe $600 (around $25/poster)? Also 22 of them have two sets of staple holes at the top - so maybe they're worth less for that?
The yellow wrapper is hard to find - maybe it's worth $100. I'm looking for the Gold Rush gum version and would probably pay that much - but I tend to be a bargain hunter.
IFIRC, Dan tends to run a little high on his prices.
