Bag End is the infamous abode op The Hobbit hero Bilbo Baggins and his equally adventorous nephew, Frodo, of the Lord of the Rings trilogy. As it happens, the Sackville-Baggins aren't the only ones desiring this luxurious hobbit hole.
See how much Bag End is worth and what you would get should you be lucky enough to convince Bilbo to sell it to you.
