Does anyone know where to find the best treasures? Most expensive and profitable lol? Whether it be armor or weapons or anything else, just looking to raise some coin. Where can i find good treasures?

Bandit caves, just clear them, than loot them, than drag yourself to town and sell it all. Pair them with a bounty quest and it's an extra pay day.

Best way I found to make loads of cash is with enchanting. Buy petty soul gems, get a couple decent enchantments, and put them on any weapon (they're pretty valuable even with petty gems; armor & jewelry take higher level gems).

Couple it with making weapons and you can level up quickly while doing it. You can make enough off of an enchanted iron dagger to buy enough materials to make & enchant a couple more... and once you get up to 100 enchanting and can put two enchantments on a weapon... the cash really adds up.

I'm at level 68 now, and I only pick up daggers (and daedric & ebony weapons), because they're the most profitable per lb... a single iron dagger with paralyze & banish enchantments sells for around 1,700 for me (more to the opposite six due to the charmer perk)
