Is there a way to get the full value of 7770 out of the account?
Do you mean, how to make your Steam account to reach that value?
What I mean is to take that account and turn it into $7770 in cash.
I'm guessing that thie probably can't be done since the OP probably would have done it himself.
You're miss understood this, $7770 is not the balance of Steam Wallet (money) that he has.
It is the price of the account based on the game that he owns, so the website calculated all of the game price on the account.
So $7770 is the estimates of how much this account worth (based on the games collection)
