Sixxy that are alot of things that come into factor when putting a price on an account. Do you provide recoveries, are they any offences on the account, how trusted is the user that is selling the account. I suggest you look in the thread that is made for sale of accounts and start from there. You could also pm users who sell accounts on a regular basis and ask what they think it is worth? Those are just a few things I recommend also would the account come with any membership and/or gold on the account?
I'd say around 45m. You will have a difficult time selling since you aren't exactly "trusted". Not to blame you, but a lot of people recover accounts, vouches are sort of a cushion for that (doesn't always work, but it definitely does help)
