depends on the coin type. i look at populations of pcgs and ngc to see if there's a big difference in the % of 70's vs total graded. sometimes pcgs % of 70's is far lower than ngc, usually true with gold. the opposite has been true with old coins.

I like your set, i'm 1 spot behind you in the rankings. how often do you maintain a "70" when you crossover from NGC. Just curious, i've always been nervous to try it
