I agree, up until the date of that auction, 2019. It wasn't until about the second half of 2020 that things started going bonkers with collectible prices and all around lunacy with prices of everything. Your rationale was sound. It's become the unknown now. Time will tell. Still over a month to go on this auction. I am surprised there's a $190k opening bid. The final hour should prove very interesting.
The sale and story of the discovery coin is here, along with a list of the 1943-P examples. The way I read the list, there are 4 duplicate submissions out of the 20, leaving 16. https://coins.ha.com/itm/lincoln-ce.../1291-4362.s?ic4=GalleryView-Thumbnail-071515 This auction lists the 6 1943-S examples. https://coins.ha.com/itm/lincoln-ce.../1298-3703.s?ic4=GalleryView-Thumbnail-071515 And here is the 1943-D example along with the stories. You can make offer of $1.26 million or more if you want it. https://coins.ha.com/itm/lincoln-ce.../1326-3005.s?ic4=GalleryView-Thumbnail-071515
