I wouldn't expect much for the purple crystalline.
But if that gold one Is non-inscribable (OS) then you have hit the mother load, and are 100a+ better off. If it's inscribable then 350e (ish?) I'm not good at inscribable crap If it's os, don't sell it to private offers, you'll get low balled and rip yourself off spectacularly.. list it for sale here.
