My conclusion after reading all of the posts regarding my original post is that the border and inset colors have to match up and are in multiples of 11.

Therefore, either the print runs for Series 6 and 7 are wrong in the price guides and should be 447 - 511 (with the appropriate 431 checklist) for series 6 and 512 to 576 plus 509 checklist for series 7 or Topps inserted a lot of DPs in both series 6 and 7 to make the colors match (I find the latter hard to believe).

The SPs currently listed in price guides for the 6th series, despite being accepted for over 50 years by the industry, just don't match up with respect to border colors and certainly don't occur in multiples of 11, so I question their validity.

If the number scheme I proposed for the print runs 6 & 7 occurred, the colors match up and no SPs occur. My fervent hope is that some uncut material for either series would be found so we can ascertain what actually transpired.
