How much would an account with the following games be worth?

I've had a spare account that I haven't used in a while since it was VAC banned on HL1 engine games, but it's got hundreds of dollars worth of un-banned games on it. I am not thinking of selling it at the moment as that'd be breaking the TOS, but can anyone tell me how much they would pay for this account?

It's got the following games:



ARMA: Combat Operations
Audiosurf
BioShock
Call of Cthulhu: Dark Corners of the Earth
Call of Duty 4: Modern Warfare

Note again that it is VAC banned on HL1 engine.

 

Unfortunately, the VAC Ban brings it down to around 30-40$ even with all the games.
