Atari 5200 Prototype cartridge

Hello. I'm selling off my video game collection, I am ebaying most of it, but I wanted to offer this item here as for some reason Ebay won't let you sell official prototypes.

The game is Real Sports Tennis, it is the lab loaner of the finish version, so it plays the same as the regular one. One of a kind piece, but a proto of a common game.

I am asking $60 for it shipped. I ship via Fed Ex ground to the U.S. only, my account is not setup for international. PAYPAL ONLY

Thanks
