No it just states you entered a valid key that will be given once it's done, it does not validate if it's used or not.

So I checked an old humble bundle of mine and I realized I had a mirrors edge I can put on steam gifts. Only thing is is that I'm not sure if the key has been used or not. I checked my profile and I've never gifted it, I even started creating the giveaway and when you put in the key it says "one key found". So does that mean it's an unused key? If not. How do you check/know it's unused key?
