They vary in price greatly because the Rookie Sensation cards were one per box inserts. The value should be in the $15 range normally but the 2011 Champions series had woeful packing and there appears to be about 3-4 Gillett Rookie Sensations for every 1 of the other players....which is why the Gillett can be picked up a fair bit cheaper and the others push up a little higher. I think i have about 7 of the Gilletts
