And to add a few thoughts of my own as I think I was one of the old crew who actually cared about the backs, back in the day ...well, at least about 15 years ago. I have actually seen more blank backs than SN backs. That aside there are a few different Everybody's and Gimbels backs, that have a different type printing, which I would put in the most scarce category. And with everything seen over the last few years I am not sure Gimbels isn't currently near the top of the toughest back list. The chase is half the fun. This grouping isn't complete but it's close...
