Slabline™
Graded-card protection score
Slabline™Sign inTrade Check →Every “rip a graded card” platform, what it actually publishes, and the expected value of a rip from its own odds. Then the part they don’t show you: whether the buyback offer on the slab you pulled beats selling it yourself. Free — no account.
Operators profit only if the cards in the pool average less than the pack price at their valuations — Packz’s own published odds put 69.6% of rips under the price.
“90% instant buyback” means you sell back at 90% of a number the operator set. Take it every time and the expected return drops another tenth.
A $100 pack with EV “$100” at the operator’s FMV is a $85 pack if their FMV runs 15% above real comps. Check the pull against real sales before you accept an offer — that’s what Buyback Check below does.
Start from a platform’s published odds, then tune the price, the buyback and how much you trust their valuations.
Every band and percentage is published on the pack page (same shape on all 12 packs, $25–$1,000).
Operators’ own odds and valuations, arithmetic ours. Odds change with inventory — read the pack page before buying. Entertainment, not an investment; not advice.
Type the cert on the slab you pulled and the buyback they offered. We price it from real comparable sales and compare against what you’d net selling it yourself.
Read from each operator’s own site on 2026-08-29. Odds move with inventory; a platform that publishes full dollar-band odds lets you do the math before you pay.
The category most likely to disappoint — a graded 8 of a common is still a common.
