Perfect Zodiac Sword

Just bought one of these, here are the stats.

Gold, Max Damage Sundering Zodiac Sword of Fortitude:

Req. 8
15-22 slashing Damage
15^50
20/20 Sundering
+ 30 Health

I know it's worth a ton, just how much exactly i'm not quite sure.

Sorry, part of the stats were a little of so i edited it.
