(World of Warcraft) Benediction Staff (Priest)

I am looking to sell an account that has a variety of WoW mounts/items etc & a strong OW account attached to it that all increase the value but I am struggling to find anything on the old and now unobtainable Priest staff "Benediction"

The account has a Priest with this item and it seems to have been somewhat special.

Does anyone know what the character/item may add to the overall value of the account?

Thanks in advance.

 

Still hoping for some insight if anyone has any idea at all, thank you
