(adsbygoogle = window.adsbygoogle || []).push({}); It currently has Half-Life 2, Half-Life 2: Episode 1, Half-Life 2: Episode 2, Half-Life 2: Lost Coast, Portal, Team Fortress 2. How much would it be worth?

Give or take 30-40. Cant give an exact estimate.

10-35 dollars depending on the buyer.

All you have is the orange box. So pretty much $30 MAX.
