If this hasn't been botted this would be worth around $65.
Is the account a combat level 3 account? Please state all the other stats on the account and I'll try to get a more accurate price check going for you.
I'm currently getting 99 hunter on the account (87 currently) and was interested to see about how much it would go for. It doesn't have very high other stats - only ones worth while would be mining/smithing/crafting - which I trained mining for a bit as well as smithing. Crafting came with treasure hunter.
