Rough Idea what this is worth? 1962 bottom and a 1963 Top. No keys for locks and top lock hasp is missing a pin for the bale but works with a nail. Just don't need anymore. Sorry about the pick, first post.
Pretty common here probably because I am really close to both manufacturing sites, I have 2 stacks and paid $125 for one and $75 for the other, but both mine are a few years newer with the square badge, same boxes though.
I bought a similar stack for $175. I didn't haggle and the seller seemed quite happy. The $150-$200 puts mine right in the middle. I don't regret the purchase and really enjoy the set. Yours are in slightly better condition and have more drawers than mine. I'll bet someone will pay $200... depending on your location, I suppose.
Paid $90 for mine at an auction, including the mid box and they were completely stuffed full of tools and NOS GM (Pontiac) GTO/Firebird, parts, decals, etc.
