So I checked how much my TF2 backpack is worth.... (Question inside, no giveaway ;.;) (Fixed)

You are way wrong, your backpack must be worth 2-3 keys.

http://backpack.tf/id/76561198008331941 is much more accurate

Those items are the value taken from the Mann Co store.
In reality, they are sadly worth around 5p each...

Worth a max of $6 USD

That value assumes you can be bothered to convert all those items into ref, and then that ref into keys and then those keys into paypal.

Doubt it's worth it tbh. :p

Launch TF2, turn all weapons into metal, find metal->key trader on TF2 outpost.
