IIRC 'Selected' denotes a hone with no blemishes, inclusions. I forget what they call the lesser coticules at Ardennes, the only current mine harvesting and distributing them. But whatever it is, they say that there is no difference in performance, only in appearance. The Select is the more expensive to this day though. The "Extra Choice" is a rating I don't recall seeing. When you get it post a close up pic. Must be a honey.
