I do not think sgc will grade
There was a time that a variation needed to be catalogued before it's graded. Not sure about now. Why not call and ask them then you will know for sure. I do not know how much research one expects for the nominal grading fees. If you expect all kinds of research etc. expect grading fees to be considerably more then current rates. Like Anthony stated do a little work try and get some articles published on it. The payoff would probably be worth the effort if you could get it catalogued. A rare variation from a popular set should realize some very good money.
