Are we allowed to sell Steam keys on the Trading forum?

I looked at the trading rules and FAQ and couldn't really find anything about this. Can I sell a steam code I don't need by writing the code on paper and then mailing it to the seller? That way I can have delivery confirmation so no one tries scamming me by claiming they never received it.

This isn't ebay. Yeah you can sell steam codes. I'd just get the money first and then PM it if you're comfortable with that. Just don't trade with some complete noob. I've sold a few codes on CAG and everythings been fine.

I think the only thing not allowed is selling an account.

Most people use this thread to sell Steam codes
