Stated another way -- when you line up all of the Heritage Black Swamp sales in PSA serial number order, and then try to align the PSA population report with those sales, you are left with some interesting gaps that call into question the accuracy of the pop reports, as well as the location of the cards with the missing serial numbers, that I don't think can be explained by crossing over. When Memory Lane has an auction this past month where so many of the cards --maybe all of them?--were previously not in those holders in a Heritage auction, and the serial numbers fill the gaps in the Heritage serial number ordering, the held back explanation does make sense in that context.
