So the Unearthed Fragrant coins you get through the researcher missions in the Caverns are soulbound, but when you exchange them for the Coveted Bauble, they become BOA. Just incase people have multiple toons are were grinding for the couple of mounts, you can throw all your baubles on one toon.
(im probably late to the party on realizing this, but i figured id throw it out there if it can help someone)
