Less crap that is worth 300gp that only sells for 15 so you arent trying to be the garbage lady from the Labyrinth just to scrape enough coin to get one thing. As a DM, I usually just give people a bag of holding that holds 300 pounds and they empty their inventories into. 5 people with EVERYTHING in a bag that holds 300. Its not until later when they find 3000sp in a hoard do they go himm...Wooden chests worth, actually worth 400gp, that weight 50 pounds, they take until something else is better value to weight. But you certainly not picking up 50sp plates and crap.
There are too many lootable things that are empty or garbage, and what is mildly "worth" it is worthLESS at a vendor because the numbers dont correlate even remotely at a neutral reputation. A chest in a room should be exciting. An "opulent chest" shouldnt have a fork and a carrot. Loot is exciting, searching bodies is a crapshoot and the DM chooses the amount based on investigation score, typically. But if there is a chest or a box or something, people should be excited about it. Something you can use like a bomb, flask, scroll, or a lot of money. D&D has 2,000 gold rings. A ring of spell storing can cost up to 25,000gp. Its a system that is infrequent but bountiful.
