Whatever you do, do NOT attempt to remove the stamps from the brown paper. Though there are stamp companies that will appraise your item for a fee (for example: Online Stamp Appraisals, Antique & Rare Stamp Appraisals - Value my Stuff), I'd first attempt to find a stamp museum and submit a pic to them for their opinion. It's certainly an oddity, but whether or not it's also a rarity still needs to be determined.

Leslie, tete-beche, aye.

Edit: Tete-Beche:
A pair of stamps printed together so that the images point in opposite vertical directions.
