How much is my Steam account worth?

Hello,

So I was searching for somewhere I could sell my Steam account due to the fact that all I do is just log-on to Steam and that's it.

I was thinking it would be around the £200 - £350 mark as I have quite a few games, here's what I have:

- The Binding of Isaac
- Dead Island
- Orcs must Die!
- Portal
- Sniper Elite
- Sniper Elite V2
- Toy soldiers
- Waves
- Battlefield: Bad company 2
- Borderlands (With ALL current DLC)
- Bulletstorm
- Call of Duty 4: Modern Warfare
- Call of Duty: Modern Warfare 3
- Counter Strike: Source
- Garry's Mod
- Garry's Mod 13 (Beta)
- Gotham City Imposters
- Hydrophobia: Prophecy
- Killing Floor
- Left 4 dead 2
- S.T.A.L.K.E.R.: Shadow of Chernobyl
- Section 8: Prejudice
- Rhythm Zone
- Turba
- Breath of Death VII
- Cthulhu Saves the world
- Puzzler World 2
- Flatout 2
- GRID
- MX vs ATV Reflex
- Smash Cars
- Warhammer 40K: Dawn of War - Gold Edition
- Warhammer 40K: Dawn of War 2
- A.R.E.S
- Blocks that matter
- Gish
- Terraria
- Titan Attacks
- Trine
- Lunar Flight
- Train simulator 2012
- Railroad tycoon 2 platinum
- Vegas: Make it big
- Bastion
- Dead horde
- ALL GRAND THEFT AUTO GAMES
- Just cause 2
- LEGO Batman: The videogame
- Nation Red
- Prince of Persia: Warrior within
- The witcher: Enchanced edition
- Cubemen
- Defence Gird: The Awakening
- iBomber defence
- iBomber defence Pacific

There's a total of around 70 games or so.

I'm just getting really bored of video games, so I was hoping instead of just deleting Steam, sell my account onto somebody else that will actually make use of most of the games.

ALOT of money has been put into this account, I can't just un-install Steam.

So, how much do you think my account is worth, and maybe, if somebody offers a good price, I might sell.

American buyers:
I'll take no less than $160

British buyers:
I'll take no less than £100

 

if you sell it on ebay with pop you can get 300 usd;p
but here is blackmarket, i think 75 usd for this

 

British pounds for me. >_<

Also, you can't sell these on eBay can you, they have a Digital downloads policy?

 

ye , tried to sell mine , got instanly deleted ( the action ofcourse )
