Case in point - someone buys the SGC 30 Mack, which is way off center and has it crossed over to PSA, knowing it will get an OC or MC qualifier, to show that it is otherwise crease and defect free.

The original run of Heritage Macks graded by PSA are all shown with serial numbers in the 19871820s, 30s, and 40s.

The new PSA holder carries the following serial number — 25420189 —totally out of line with the others in the family.

So clearly PSA is not holding spaces for Black Swamp cards in its serial numbers (if they were Mack would’ve slotted back into its original PSA case - assuming there was one before the SGC version wound up on Heritage). If they’re not being held out of circulation for some reason, like the Memory Lane Black Swampers, then maybe they were initially graded by PSA and then removed from circulation (and the pop report) and graded by SGC before being sold. If you add the Memory Lane Green Davis as well as the four SGC Green Davises on the Heritage website, you are then left with just one space in the series - one heretofore undisclosed E98 Davis Green Swamper.

I find the whole distribution of these sharp little buggers to be really interesting. And I do wonder whether there are more out there to be sold in future auctions.
