I couldn't sell these for 1 btc just in case people wanted to know the ballpark market rate. There are so many avenues where you can get these free that they are essentially worthless.
1. Stop thread crapping - do you really have nothing else better to do? (looking thru your past posts I'd say no)
2. Last time I sold one of these I got $70 in BTC for it so must not be that worthless. Your failure has nothing to do with me.
Is it the one use per account kind or is it a true gift code?
I believe this is a PROMO code so you may need to use a new adwords account to use it.
