So I have no idea on Lioden economics/prices and how they go about, but i'd like to know what I should sell her for

I have no idea what rarities/markings etc are worth, since while my account isn't new I've only really started playing here this august, so I'm still a newb in respect to pricing ranges and such - so sorry if I come off a bit dim on subject matter? cx
