Copper #2 is a lower grade than Bright & Shiny, covering copper that has light impurities — paint, solder joints, tarnish, thin coatings, or minor corrosion. It includes items like soldered copper pipe, painted copper sheet, and lightly contaminated copper fittings. While still valuable, Copper #2 is discounted because the impurities must be removed during the smelting process, which adds cost. The price difference between #1 and #2 can be significant — often $2–4 per kilogram — which is why sorting and cleaning your copper before visiting endless metals is one of the fastest ways to increase your payout.
