What is the Slabline Score?

The Slabline Score is a credit-style 0–1000 protection score for a graded trading-card collection, blended from five weighted factors: Insurance (35%), Concentration (25%), Storage (20%), Liquidity (10%), and Provenance (10%). Higher is better; bands run A (≥880) to F (<400).

How does Slabline value my graded cards?

Each card is valued from recent comparable sales for the exact graded card (by certification number and grade), aggregated across eBay, Heritage, Goldin, and PWCC. More comps yield a tighter, higher-confidence value.

Quick-sale recovery

≈ $1,065

60% recovered

A dealer typically pays about 60% of market for a fast, guaranteed sale — the rest is the liquidity gap. An auction or private sale can recover more but takes time and fees. It’s why your Slabline Score weighs liquidity — and why insuring at market matters: a fire-sale recovers far less than the number you’re covered for.

Estimated from dealer buy-vs-sell spreads; actual offers vary by condition and demand.
