Steve, They are a sport of Gold Hahnii. I have 3 so far. Keep looking. Some over grown plants that are over crowed seems to sport some of these. They are getting more common now. I wanted one for years myself then saw one on ebay last year as a pup on a Gold Hahnii so I purchased it and got just as pictured.
Later while traveling in Ohio, I stopped into a road side nursery and saw a bunch of very well grown 4" pots of Gold Hahnii and one with a Solid Gold pup! And they were selling for around $5 each. If my wife wasn't there, I would have bought all of them.
