So today I cut open my 1 BTC bitbills. When I opened them up there was a private key printed on the back of the QR code. I entered this into MtGox and sold the bit coins. Nice and easy! 
BUT...
Then I cut open the 5 BTC bitbill (same as I did for the 1 BTC bitbills) but this one didn't have the private key printed on the back of the QR code. So I had to try and get the silver stuff that was left over from the sticker/hologram off the QR code and during the process managed to damage the QR code. I have tried multiple times to read the QR code with my phones camera but no joy. I guess I have just lost 5 BTC eh?
I have to say, what a stupid design for the 5 BTC bitbill. Why didn't they print the private key on the back like they did with the 1 BTC bitbill???!!!
