While I cannot give you an exact price, important factors to consider when selling any account:
-black marks/botting strikes (these seriously lower the value of the account especially if the account being sold is meant for botting purposes)
-how many vouches you have (lowers the risk of recovery raising the price)
-hand in hand with above: whether you are the original owner or whether you are not the original owner.
Any other useful information such as any items that come on the account could play a factor. Updating your post with this information would help a user active in account sales give you a more accurate price check.
