Just a little twist on Zunath's Script for getting gp from a trash barrel.
With the port-o-pawn, you activate a Unique Power item in inventory that spawns a placeable. Open the placeable (a black barrel) and drop in unwanted items - they will be gobbled up and you will receive a percentage of the gp value of the item. The port-o-pawn will self destruct in 60 seconds or when closed, whichever comes first. Both the destruct time and the gp percentage are editable.
Includes a demo mod.
Should work on all versions.
