There is not much to know, the other two tins are mid 1950's, so I would think the Zig Zag would be around that time too. The advertising looks mid 1950's to early 1960's. The Zig Zag tin could probably bring $20 from someone who collects Zig Zag stuff, not being in the best shape. The other two tins could bring $10 to $15 each. These tins don't hold a lot of value but look nice in a collection either way. I have a few of those other two tins, but no Zig Zags!
