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.

Does Slabline sell insurance?

No. Slabline is software that produces broker-ready insurance schedules and risk reports. It is not an insurer, broker, or appraiser and does not provide insurance, financial, or legal advice.

Which cards and categories does Slabline support?

Graded slabs from PSA, BGS, SGC, and CGC across baseball, basketball, football, soccer, Formula 1 / racing, hockey, Pokémon, and Magic.

How much does Slabline cost?

There is a free Ledger tier for up to 25 cards. Collector is $99/year (or $9.99/month) and removes the card limit for an unlimited collection. Insured is $149/year (or $14.99/month) and adds broker-ready insurance schedules and a weekly intelligence brief. A Vaulted tier adds connected Hobby Smart Case hardware.

What is the Hobby Smart Case?

A connected travel case (Travel 40, 75, and Pro) with per-slot temperature, humidity, light, and tamper monitoring, plus GPS location and a chain-of-custody log — turning storage risk into live, sensor-verified data. Launching Q4 2026.
