Registry Set Magic Numbers

AllCoinsRule

Definition: A registry set's magic number is the highest number in the pop higher column. So for every date and mint mark, the number of possible pcgs graded upgrades, are equal to or fewer than the magic number.

For example the Land of Smiles Liberty Nickel Collection has a magic number of 8 due to 8 higher than his 65+ 12-s.
My 1980 mint set's magic number is 3 due to the 3 higher P SBAs.
The DRG SBA set has a magic number of 0. Every single coin is a top pop.

I know one Lincoln collector who likes to collect by magic number. He's always looking for the coin that has his maximum pop higher. His Lincoln Memorial set now has magic number 19.

Interesting concept. Sounds like something a mathematician would come up with ...

Bubblehead

Or... a Navy Cryptologist!

And this will work in reverse for Lowball sets

The magic number on my Complete Dime Complete Variety Set would be huge!!!

So in reverse, the magic number for my Lowball Peace Dollar set is 0 ?
None graded lower.

The magic number for my Complete Kennedy Varieties set is 25 (although most of them are much lower; I don't care much about those late Satin Finish coins). I need to get to work.

Cool concept!

(Although for clarity I would say the "highest number" in your definition rather than the "maximum number," if I understand you correctly. The "maximum number" for any issue could change as more examples are submitted, the "highest number" is a snapshot of Now.)
