Live card listings are pulled nightly from major marketplaces — prices, grades, sellers, and card details.
Our scoring engine compares each listing to 90 days of sold comps for that exact card and grade. The result: a 0–100 deal score.
Grand Slam (80+): buy with confidence. Extra Base Hit (50–79): solid deal. Strikeout (0–49): walk away.
Try it — no account needed
Every listing on hotcorner gets scored against real sold comps — Grand Slam (great deal), Extra Base Hit (good deal), or Strikeout (overpriced). Filter this sample board the same way you'd filter live listings on Scout.
Sample listings shown for illustration — live scores update nightly against real sold prices.
Why hotcorner, not just a price guide
Sold-price lookups are table stakes. The part nobody else does is closing the loop from “that's a deal” to “it's in my collection.”
Not a historical average — every active listing is scored against real sold comps the moment it appears, and sorted straight into Grand Slam, Extra Base Hit, or Strikeout.
Stripe-backed and already running. Deposit funds, set a max price and minimum score on any Watchlist item, and Wallet executes the purchase the instant a match hits — no refreshing, no missed drops.
Every auto-buy lands in My Vault. Ship it home, hold it in the vault, or list it for resale — all from the same account, no separate marketplace required.

For live break bidders
A team spot in a live break is a bundle of ordinary cards most bidders aren't pricing — it has a real, computable expected value whether or not it produces the big pull. Toggle spots off as they sell and watch the pool's value update.

We score graded and raw cards separately — a PSA 10 and a raw card never compete for the same score.
