The Coffins were Klaus' most prized belongings. In four of the five coffins, there was an Original vampire, each daggered with a white oak ash dagger. Niklaus had neutralized each one. It is revealed that the last of the five coffins, the spell-locked one, contained Esther. As of now, all five coffins are open.
The coffins were first seen at the end of As I Lay Dying, when Klaus was about to leave town with Stefan. At that time he had 5 coffins (Rebekah, Kol, Finn, one locked and one for recently-Daggered Elijah).
In The End of the Affair, Rebekah was resurrected and after she has found that her necklace was missing she destroyed hers leaving four coffins.
At the end of Homecoming, Stefan took the coffins to a witch house to blackmail Klaus. Stefan and Bonnie tried to open the fourth coffin with no success.
In The New Deal, Klaus acquired another coffin for his sister, Rebekah. Bonnie also had a dream about Klaus' coffins and had additional dreams about them in The Ties That Bind. Thanks to Bonnie's tip, Damon was able to steal the magically sealed coffin and was able to undagger Elijah before Klaus' arrival.
In Bringing Out The Dead, at a dinner in the Mikaelson mansion Elijah and Damon freed Kol, Finn and Rebekah from their coffins. Each awoke with a vengeance against Klaus.
