I just sold an ETK 800 Series Trading Card for about 70 Cents! Get those cards, and sell 'em! (Also, I'm gonna buy what I sell once the price goes down, which it will)
Which ones did you put up (which one is cheapest) and what's your steam username? I'll buy one off of you
Okay ... I'm now at 313 hours and the Travel Trailer just showed up in my inventory... Looks like somewhere between 1-2 hours of gameplay will give you your second card. On a sidenote, what is a Foil Card, and would that have anything to do with the fact that it's worth ten times as many "gems" as the Hopper?
Steam Foil Trading cards can be crafted into foil badges, similar to how you can craft normal badges from normal trading cards. Other than that, it is useless, but everyone thinks they need one. They are essentially rarer trading cards. They are found the same way normal trading cards are. -- Google search
I got the Grand Marshal police. EDIT: Scratch that. I now have two ETK 800 series cards, one t75 card, one bolide card, and a grand marshal police card.
Just sold an ETK 856t for $0.57. Most expensive thing I've ever bought or sold on the market I think.
