How much would such accounts be worth?

[Baller85]

I'm currently in the process of making a rapier staker. It will be about 80 attack, 80 strength, 1 defence, 1 summoning, and 80 dungeoneering when I'm done. I was wondering what price I could possibly get for that in RSGP or cash. Also, I was wondering if there's a market for 10hp & 99 magic accounts.. how much RSGP or cash would I be able to get for those? Thanks in advance for any responses.
