Depends on the game. For tf2 it isn't since you can sell the hat, but the effects vary. Whereas for CSGO There is no differince in value from each item sold and it all depends on the cheapest being sold. CSGO when you buy a knife from scm there is no change from knife to knife that is value impacting when you click. EX: You have $100 and buy say a vanilla flip knife. It doesn't matter what the others have because the only additives are very cheap and mainly not counted. Whereas in tf2 if you have $100 and buy an unusal Backwards ballcap, you can buy the cheapest one, but 2 problems. 1 most cheap scm hats are dupes and/or cancer effects. 2.The hat you buy has a value that isnt in $$$. For tf2 SCM price doesn't help with ref and key pricing whereas with CSGO the scm is the only pricing you then simply divide the price by ~2.55 depeding on the key. That is something you cant do in tf2.
