I save them, too and I'm so proud of my brass bucket. It's almost ready to go in. My yard also has the same price for red, yellow, or coated brass. On the big stuff I just take the file to it in one place, but the little stuff like prongs, they don't question. "Ounces make pounds, like pennies make dollars" and I certainly save pennies these days. Esp. ones before '82 !!
