Unofficial Noxious Open Tibia Wiki: info, downloads, tools, calculators...
This is a list of items that can be sold at NPCs, mostly at [Loot], [Jewlery] and [Misc] shopkeeper NPCs (i.e. Benjamin, below Thais Depot) that you can find in most cities. Some items that can't be sold to NPCs but are very valuable have been added since they can easily be sold at the Market.
Noxious Token is not bought by NPCs but it is valued (by players in the Market at ~8,000,000 gp.
Here's the code to add to your Cavebot so you can loot everything that's sellable with a higher price than 500gp or higher Price/Weight of 50:
