Well I will be honest, if you took away all the invent items such as skins etc the account would not be worth that much due to the fact that people just don't buy steam accounts for what they're actually worth these days and I'm not going to be able to tell you a set price since people are different and it's all about who you find and who's willing to pay a certain price, so your best bet is to either put up a bid for people to bid on or set a price and see if anyone buys.
