Many forum members made good monies when they noticed ANACS began grading previous 66 and 67s as 68-69.
Ah, that would explain how I got burned the other way, breaking out ANACS slabs to regrade with PCGS, finding ANACS 68 and 69s coming out at 66 and 67s - and that was before PCGS tightened up their Casascius grading such that 67s are now very difficult to attain.
