That's more of a collector's item instead of something people use. It can be obtained by following a very long chain quest (not difficult, just time consuming) that might not even be working on this server. The price is going to be whatever people will pay for it, which is most likely not very much if anything. The problem is the item is destroyed upon death, so more often than not you won't be equipping it. I think when you do die, though, it revives you.
