All basic loot should once again have value with shopkeepers, clay wares, pewter forks, glasses, bottles, silverware ect. If implemented, roleplayers can being a "clay wares trader," or "pillow trader," ect. The player who wants to be a theif will find a value in slipping the housewares from the kitchen of the Royal Court, or breaking into a less wealthy NPC's home, dungeon explorers can sell off the extra loot they find, the list goes on.
These small items will also bolster the economy within towns, which are to be separate and overhauled (according to Bethesda.) Rather than have a single general store, the mill may sell bread, while the clay pot trader sells clay pots, ect.
On the other end of the totem pole, rare and unique weapons should retain they're rarity and value, as they have before. A top of the line sword should not ever be easily accessible, but should carry a value that represents that fact. A player could make a choice, keeping the unique weapon, or selling it in order to outfit themselves with a large variety of other items.
