Certainly not holding my breath. These looked the `best` from a giveaway collection.

Sorry to say there is really nothing of much value in the scanned lot. All are extremely common and are not in good shape to boot. Lot of stains, tears, pulled perfs, etc. The Canal Zone stamp has a retail catalog value of maybe 50c, but you wouldn't get near that much from trying to sell to a dealer.
