Celtic Heroes

This is a drop that we got from king vorum dreadbone. I am not planning on selling it, because I am a collector of rare items. However, I am just wondering what this may be worth. I have never seen one.

I have one and love it, would probably price it around 400-500k on my server. The value may or may not plummet in the update, it will be a collector's item but the boss still spawns meaning it can still drop and it's use will be negated by newer lux/item drops.
