One thing’s for sure though – you’ll have virtually zero replayability value with this NES test cartridge.

Amazingly enough, this rare cartridge has already hit $1,050 in the auction site, and knowing the vast number of rich Nintendo fanboys out there, this doesn’t look like the final figure. You can find virtually anything and everything on eBay, and today we’ve stumbled upon an NES test cartridge that was originally meant to “given to game stores to test their Nintendo Entertainment Systems and to be returned” upon finishing.
