I didn't say there is, but as the other gentleman said, there could be. You're probably right... it's the Prestige Set. First there is the No-S Cent, which this set does not have, and second there is a doubled die PR quarter known to have come from said sets. This, of course, does not mean this particular set has one, but is what I believe the above gentleman was referring to.
I said what I said in the context that if he was still watching this thread he would think he actually missed something and would try to figure it out.
