From Destinypedia, the Destiny wiki
A Io Token was an activity token that was rewarded from completing Public Events, Adventures or Lost Sectors on Io. They could exchanged to Asher Mir in the Exodus Black for various Emblems, Shaders and Io-specific weapons and armor sets.
Since the release of Forsaken, Tokens were rendered obsolete and are now unobtainable.
