Unid Items

I'm quite confused, how do I put a price on a unid gold?
Ok, I can see the max damage and the req, but that's about it.

For example 2 things I have:
max gold fellblade req13 <-this sucks
max gold giant slayers hammer req10

This is more a 'how can I do it myself' than a PC, but feel free to evaluate those two.

Thanks

Well some guy was paying 5k for low req and 3k for high req weapons.... i would say those prices are a little low esp if you have a fell in your hands... i would buy it unid for 10k and 3k the hammer (not that i want those i'm just telling how much i would be willing to pay) hope it helps

ya like 10k for fellblade but that hammer no one wants so id it and hope for a good upgrade
