I've been building a free tool that tracks live eBay prices for all Top 100 MLB prospect cards.
Just added parallel filtering and a custom ebay search creation. More features soon.
check it out, would love feedback.

@thatchauncey@CardPurchaser Good old Big Papi. I imagine most will sell like an average 150 print run. Hot rookies and vets, like anything else, will see a premium. The good thing is they are very scarce compared to quantity of cards this set has produced.
@_a0co@CardPurchaser No, I’m pretty sure we are on the same page. I know the difference, I just had no idea they were so rare! Turns out the one I pulled is a David Ortiz Savage Sluggers. Does not sell for a ton, sadly.
Not sure if the market cares or not, but do people realize that in 2025 Topps Stadium Club, pink inserts are SSP with odds of 1:1024 packs (hobby box) giving them print runs of approximately /150? These are harder to hit than a /25 base Rainbow Foilboard, Chrome autos (up to Gold) and other types. This applies to Concentration, In Case of Emergency, Savage Sluggers, and Yours for the Taking inserts.
Happy hunting! @CardPurchaser
@_a0co This is the kind of breakdown people sleep on. 1:1024 odds with a /150 print run and most people just toss these in the common pile. Stadium Club inserts in general are way undervalued compared to what they actually are
@reqwium Try feeding the checklist and odds sheets to Grok and ask it for a breakdown including visual cues to look for each parallel/variation. It does a pretty good job giving you all the info you need.
I’ve both seen others post about this issue as well as I’ve experienced it first hand. @ebay deems certain cards valuable and/or rare enough to warrant authentication. Yet the item (typically raw) is not shipped from authentication carefully enough to prevent potential damage..
@reqwium I've seem some guides for certain sets where they do provide image guidance to the variations/parallels, but I can't find one for this set. I personally rely on the checklist, odds list, and images of the different marketplace listings to determine which one I have.
@_a0co I wish Topps would show a visual reference for every parallel clearly on thier site. I know ripped and Becker have checklists with some photos. But there doesn’t seem to be a definitive parallel guide anywhere.
@thatchauncey@CardPurchaser Thats a different Pink where the card background is pink and those are essentially guaranteed in a fat pack. This applies to the inserts where the Stadium logo and player name are pink foil.
@_a0co@CardPurchaser You mean from fat packs?? Come to think of it, I think I have only hit one and it was turned backwards so… off I go to look for that, I guess.
Sources indicate that Iran’s new Supreme Leader, Mojtaba Khamenei, has been critically wounded in an airstrike.
He is reportedly in a coma and has lost a leg. This strike sends a powerful message that no leader is beyond our reach.
In the end, America has won the war.
@B2Doane@CardPurchaser Probably about $500-700+ based on similar vet cards recently sold (search 2026 Topps Series 1 Foilfractor). I sold an Elly 1991 variation foilfractor at auction for $710. A similar Jackson Chourio sold for $700+ too.
@CardPurchaser pulled my first 1/1 yesterday… still in awe… what are the best way to get comps on something like this? I checked eBay but obviously harder to get comps on 1/1’s
