Auras in objects are not uncommon, although it does seem rather surprising that they would have one.
Since objects don't have emotions or personalities, their aura usually represents something else. Depending on the object, it could easily be the aura of the last person that used it or touched it. These auras may stick around for a long time, or they may fade quickly. It all depends on how often that person used the object.
If an object is used by more than one person normally, or a person who doesn't normally use it just picked it up a few minutes ago, the auras will not remain seperate bit will merge, forming an aura that doesn't really mean anything at all.
Unless you are 100% sure of who last used the object in question, auras from objects typically aren't anything information can be gotten off of.
