This leads me to wonder if for every modern coin, there is ALWAYS going to be a very small population of the highest grade. Why can't there be a large population of the highest grade, at least for a few years? Is it realistic that there'd only be a few coins of the highest grade for every single coin year and mintmark known, or could that be from some TPG quota to keep customers interested in gambling with the grading lottery? Let's stick to business strike coins that come in Mint sets. How could the Mint naturally create only a select few coins of the utmost quality? Are working dies different enough that for some, every coin created is inferior? Why would packaging and handling be so different for some coins but not the others? I can't imagine a variation in creation at the Mint so large that an extremely tiny amount of coins come out elite. We can't forget that graders are likely looking at so many coins per day that they see coins in their dreams. Are they given incentive to avoid assigning upper echelon grades?
