I haven't found any comprehensive source for ticket comps.
Another one that may have some value is
https://130point.com. It is similar to an ebay search engine but it pulls in some catalog auctions as well. It will also reveal the paid price for ebay Best Offer sales.
I participated in that Top 100 ticket poll that Michael posted. It was conducted at the end of 2022/beginning of 2023. There was no guidance - everyone was free to use their own rationale for ranking. No doubt that there would be some shifting if it were redone today. Value played a role in the rankings, but there are tickets that have since sold for six figures that don't show up on the list. The 1934 Masters Tournament ticket is one. Only four known and one is in the Augusta Golf Club. One sold for $600K in 2022 and an autographed one sold for $470K in 2023.
