Can I sell a random steam CD key?

Well I received CD key of a game I don't wanna play can I sell it anyhow?

you can just copy it and give or sell to anyone

You can sell it easily at https://www.kinguin.net/

Yes u can

As long as it's not used why not?
Or you can be a champ and just give it to someone who might actually play it :D
Choice is yours

i dont see why not

never knew you can actually sell these stuff...
