"A box without hinges, key, or lid, yet golden treasure inside is hid."
One of Bilbo's riddles to Gollum, from The Hobbit

Dragons, Trolls, Men, Orcs, and Dwarves of Middle-earth all had penchants for accumulating treasure. In all likeliness, the items procured from plundering would be taken and hidden in holds and hidden vaults. Glaurung's hoard in Nargothrond, Smaug's lair in the Lonely Mountain, Moria, and the troll-den mentioned in The Hobbit at which were found Elven swords would all serve as illustrations of this.

Portrayal in Adaptations Edit

In The Hobbit: An Unexpected Journey, Thorin's Company hides a chest of treasure taken from the trolls' hoard inside the ground of their cave in the Trollshaws. In The Hobbit: The Battle of the Five Armies, Bilbo and Gandalf have evidently retrieved the chest, and Bilbo takes it on his return home.
