Oh anybody who can figure out what to do is free to post it. Believe me, you're not going to match what I have. I have the same shader doing several golds, several coppers, several brass, bronze, silver, platinum, steel - in all of these I have various finishes (smooth to blurry/rough).  I have grain and mottling where needed. I have the specular node perfectly tuned to match the blur and IOR so that reflections of Poser lights look just like reflections of a Poser glowing sphere. I have several hammered versions that are really beautiful. I don't know of anybody outside guys at Pixar who can match what I'm doing. Not even at SM.

Looking at yours, Miss Nancy, I see:

There is diffuse there in your shader. I measured it on real gold - polished gold diffuse response is less than .1%. Get rid of that.

You don't have the right change in color as a function of viewing angle. That was really tricky and took me a long time to get right.

Did you use the color I gave for straight on? It seems to look a bit too green. That looks more like brass.
