Hi! im new to the scrapper world, well sort of ive been a scrapper for about a month, scraped some small stuff, keyboards and just scraped an old Boxy Monitor, i got a lot of copper and a small ammount of breass out of it, as well as some gold plated boards, i plan to sell all my gold plated boards once i get enough on ebay, but when bringing ammounts of copper and brass wire E.T.C to a scrapyard will they sort it out to make sure its all copper, then weigh it and pay me by the LB or what ever mine does? cuz im not perfect yet at sorting metals im hopeinh they will confirm it for me, am i correct on this? or no
