Zaishen Medallions

Yeah.. I was wondering what these thigns are worth ea.

Figuring that a celest sig costs 30k and that it can be gotten with 10 B. Flame or in other words 500 Z.Medals i've figured the value or each one to be 60g. But seeing as how they were useful only during the NF PvP event I'd say currently they're worthless.
