The advice about grade and cleanliness is accurate, but the post is essentially an advertisement dressed up as guidance, so it's worth being careful. Copper scrap pricing is genuinely driven by copper content and contamination — bare bright wire commands the highest price, followed by #1 and #2 copper, with insulated wire valued much lower because you're paying for plastic you can't sell. If you're selling scrap, the main question is whether the buyer is pricing per pound of actual copper or per pound of total material, because that distinction changes the numbers significantly. Also worth verifying: whether the buyer is licensed for scrap metal dealing, since regulations vary by jurisdiction and unlicensed operations create legal exposure for sellers. There's a discussion on https://lucky-misters.co.uk about evaluating suppliers based on verifiable credentials rather than marketing — the point about confirming licensing before transacting was well-made. Are you buying or selling?
