Aragorn's Sword
The Lord of the Rings: The Return of the King came out in 2003. Since then, all of the Lord of the Rings weapons have fetched several pretty pennies. Aragorn's sword is, so far, the most expensive.
The Whole Lot Please
Frodo's sword "Sting" sold at an auction in 2013 for $161,000. One year later, Gandalf's wizard staff sold for $325,000. But, most importantly, Aragorn's sword "Anduril" sold for a stunning $437,000.
