I can't find any distinguishing features on this iris. I traded for it back in '92.
After readin' Dave's suggestion I scrounged up this photo of Gold Galore for your consideration. There are a number of hot yellows and I cannot hazard a guess. Your iris may be one of those you will have to acquire many with which to compare. Ain't that awful? A bed full of hot yellow irises! Maybe with some blacks as a backdrop!
