Steam Community Beta Access

I may be wrong, but I think no, who will pay something for thing, that have no use?

No worthless

Activating will give free steam wallet /s

It has no real value. But some people like collecting the worthless crap like that and finished beta invites, so who knows. You might find someone who wants it. Just don't expect to get something as valuable as Bad Rats when trading it away.

You might ask this on steamtrades, people there are more into this stuff, but I think that the price is around $0.02

I have a Steam Mobile Access Steam gift, I doubt it's worth anything but I'll just keep because, why not :)
