Dwarf Mail:

Bilbo Baggins' coat of mail, given to him by Thorin Oakenshield. After his adventure, Bilbo loaned the mail to the Michel Delving Mathom House. He retrieved it before leaving on his 111th birthday.

In Rivendell, Bilbo gave the mail to Frodo. It is not know whether he took it into the West when he went with the Last Riding of the Keepers of the Three.
