According to the description, the chip has an internet code that basically unlocks an account, allowing you to redeem the designated quantity of bitcoins and transfer them to your account. I see plenty of opportunity for mischief and no one to help you if you get cheated.

I had a stack of copper 1-ounce rounds with a bitcoin design; I sold them for a few bucks apiece on Ebay as novelty items with no bitcoin value. I suspect they were a better investment (for their copper bullion value) than these chips.
