Standard for the game. Chests, sacks, normal mob corpses, coffers will generally have vendor trash items, alchemy ingredients, food and/or small amounts of gold. I have noticed small coin sacks all over as I explore - those often just have 5 or 10 gold, but some have more, I have found a few that had 30 ro 40 gold in them
If you clear a cave or whatever, you usually find a decent chest with something good for your level (not necessarily use-able by your character though), or if there is a mini-boss, like a bandit chief or full conjurer or something, their gear is usually nicer quality and leveled appropriately.
