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?

Quick-sale recovery

≈ $182

30% recovered

A dealer typically pays about 30% 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.
