How much does grade and purity actually affect the price for the same metal?
Short answer: Significantly — the benchmark price assumes pure, refined metal, so contamination, mixed alloys, coatings, attached non-metal components, and general impurity all reduce what a buyer can realistically pay, sometimes substantially, which is why two loads of the "same" metal can receive very different offers depending on how clean and well-sorted each one actually is.

The benchmark price is for a specific, defined level of purity — any deviation from that (alloying, coatings, contamination) means the buyer is receiving something worth less than that reference standard, and pricing has to reflect that.
What commonly reduces grade
Paint or coatings, attached plastic or rubber components, mixing different metal types together, and oxidation or corrosion are all common ways real-world scrap falls short of pure refined metal.
Why sorting effort pays off
Cleaning and separating material before selling — removing non-metal attachments, keeping different metal types apart — moves your material closer to the higher-value end of the grading scale, directly affecting what you’re offered.
