Crossover For ATB Question

Excellent question solo...POLITICS...from what I've read, from the guys that do this(with smaller denomination coins, like Morgan $1), the success rate is higher if sent in raw...there is some sort of bias against anacs, ngc slabbed sent to PCGS as crossover...not SUPPOSED to be, but, the math I've seen is there to prove it...sad, but true. I may...may..try it on 1 ATB, and, see what happens...the coin in question would have to be examined carefully prior to sending, or, just not worth the funds involved....so, need to ask the sellers....is this average for the grade, below average, or, above average, and, hope for an honest answer...or, wait to see in hand at coins shows, to determine myself(preferred).
