how do stones and solder and affect the price given for scrap.For example the prices quoted are for clean stamped, what about all that unstamped or mixed scrap . what sort of diffrences should you look out for.I guess its best to sell clean as seperate and impure but what kinda price diffrence should someone expect i also see that the refiner will charge a price for testing all the unstampted it takes in, how much of a percentage would that be about. thx all jimmy
