The seller has finally decided to begin the auction at a price point well below sustainable value, typically a wise move. Collectors want to feel they have a chance at a bargain, so starting items at a fully valued price typically ends in a cycle of listing and relisting. This boxed set from Dennison first began being sold in 1928. The design lasted just a few seasons accounting for how hard it is to find this set. The fact that the cover cut-out has become dislodged is not material as it is present and can be re-attached. Sustainable guide value is $325. This seller is known to me as conscientious and wanting to convey accurate information. One should feel comfortable placing bids with them. (Go Blackhawks!)
09/11 Update: Inexplicably, this great set brought only $152.50.
