He did concede the point about grade rarities, but other than those he is right, there are no great rarities in the ASE series. Best it has are the 1995-W proof and the 2019 (S or W can't remember which) reverse proof. In the bullion coins the best you get is the 1996 with a mintage of over 3.5 million. The only "rarity" that wasn't specifically made to be a collector rarity is the 2008 rev of 2007 Burnished, and it was still a coin specifically made for collectors, it just happened to be a variety as well.
