I saw the bigger recent sales and sold my duplicate for $150 in late October. I bought it for something like $40 in Aug 2022. It’s not even in particularly good shape (big crease, bad corners, stained back) and a raw Piedmont 350/25. (I kept my better example)

This was a legit auction with multiple bidders.
I don’t know the etiquette of “outing” a buyer, but they are “in the business”. I’m guessing there is something to this (maybe new variation??) but I don’t really care about variants and am happy with tripling my investment in a year.
