This a link to the PSA registry site which lists the HoFers in alphabetical order. Forget all the values which are related to scarcity for the signatures and just use it as a list of HoFers, it is up to date with this year's 4 electees already listed. The top part is in black, they are the "readily" available autographs with no mention of value. The bottom part is in red , they are the ultra rare signatures ( it includes some that are unattainable and some that appear in the market rarely). The weighting given each signature as to rarity is by no means scientific , it is just the opinions of the people who have submitted their collections to PSA for ranking.
I think you will find it helpful and the weighting scores are interesting and a good conversation starter.
