The price guide value says $600. The last 2 auctions were $122.50 May 2020 Ebay, and June 2019 $156. Beyond those sales, I haven’t been able to break $250 in the past 3 years, and haven’t seen $600 money since 2015. It would seem they should base tier value on auction values and not some arbitrary made up number. Having sold the majority of this coin, I try to select tier based on what I think it’s worth and not based on price guide values. Now I suppose if it graded higher and price support was shown for an up charge I wouldn’t mind, but using an arbitrary price a point difference considering grading fees can eat half the coin. How are you guys selecting tiers?
