help me price necro helmet

Hello everybody,
I always been playing SSF new leagues, never cared about prices, market, trades etc. But learning builds I kind of think I had some serious luck with this helmet....

just out of a curiosity (btw second attempt with bound fossils)... how would you price this one?
