well if yoru imperial and have lockpicking perks im sure you could get around 250 gold from a master chest, but i have yet to play an imperial or perk lockpicking and ihave not found any decent loot in a chest

whereabouts is that one?

Think I stopped looting urns after about 100 hours or so. 2-3 gold at level 50, yea right, like that's worth my time. I'll just go sell my ebony loot instead. Not much worth looting at all tbh, except from named enemies or deathlords and at the treasure chest at the end of a dungeon.

And the one containing 20k has to be after a certain questline, of which you actually only keep like 19k (because of certain expenses)
