The Mythril Circlet is a Circlet-class head armor found in Golden Sun. It is found in a chest in a locked room in Lunpa Fortress, behind a locked door that can be opened with the Cell Key, but the first time you pass by this door you will not have found the Cell Key yet, so you must remember to backtrack once you get it. As a Circlet, it can be equipped by Ivan, Mia, Jenna, and Sheba. Its buy value is 7000 coins and its sell value is 5250.
