Don't know if the golds on this page are exactly what you're looking for, but I think this guy's metal textures are beautiful. I agree with bikermouse that looking is a great way to learn. Even if I don't use a particular texture that I run across, I do learn by applying it to a primitive and then going into the DTE. I try to decipher what settings cause the various characteristics. Most of it's still Greek to me, but I'm slowly catching on. Good luck!
