MSIA Zeta Gundam Titans Version

[lt_amuroray_5114]

So I was considering going on a hunt to find and purchase one and it led me to wonder, Since this item was not sold in stores and could only be won as a prize... what is a decent asking price for one and how much are they actually worth? I've seen some prices in the past range from 60 to the Hundreds for one... but what is the actual worth for one?
