Although this topic has been discussed, I have to ask...
Why not have a happy middle? I'd think one could cut the regular multiplier in half and get a fairly adequate idea of how the HOF cards could be valuated.
I'm painfully biased as I have a couple semi-sorta-kinda-rare backs (Old Mill, Sovereign, Sweet Cap. Fact 42, Sweet Cap Overprint). Among them a Walter Johnson PSA 2.5, Nap Lajoie Portrait PSA 3 and a Christy White Cap PSA 5 (along with others). According to the regular multiplier the values go up to x1.8 if they were commons, but x0 if they are HOFers.
Surely the market would command a small premium for HOF semi-sorta-kinda rare backs? If I saw my Walter Johnson Old Mill and a Walter Johnson Piedmont Fact 25 of the same grade for the same price, I'd buy the Old Mill every time. I'm thinking most folks would. Shouldn't there be a slightly higher value if that is the supply/demand?
Maybe I'm just bitter that when I first heard about the rare backs years ago and flipped my cards over I discovered nothing mind blowing
