The quest “Numismatics”
“Bring Misprinted Draenic Coins to Krom Stoutarm in Ironforge. Misprinted Draenic Coins can be found when completing your first Random Heroic Draenor dungeon each day.”
Cannot br progressed as running random Shadowlands heroics do not update the quest.
As you may remember, this quest has been updated every expansion (Legion & BfA) to account for current random heroics to progress the quest line. That is not currently the case with Shadowlands.
