actual plausability of selling a steam account?

hey, so, i've got a pretty average steam account. there's really nothing special, maybe 1 or 2 AAA games, lots of indie and other titles. roughly 60games or so, worth about ~$400. the only real selling point it has, besides the games, is the fact that it's over 7 years old. what's the likelihood anyone is gonna buy it? i probably won't sell it for it's value, anyways

I wouldn't recommend it. You can retrieve the steam serial codes from each game and paste them into a doc. Then delete the game from your steam library and copy/paste each code into Kinguin (SteamCode Selling Site) and sell the games that way.
