Great job. All of this should now prove that the 6th series is 447-511 at 66 cards, 22y, 22r, 22b, and the 6th series is 512-576 at 66 cards, 22y, 22r, 22b, and there are no SP's in either series. I have a feeling that is going to be difficult because it has been accepted for decades that the 7th series starts at 523 and that there are SP's in the 6th series.

Great stuff. The 63 is aided by the colored base. If only 66 were as easy.
