For brokers & insurers

Underwrite graded-card collections with less friction

Slabline turns a client’s shoebox of slabs into a clean, valued, risk-scored schedule they hand you — ready for intake and renewal. You spend less time chasing values and more time writing the policy.

The intake problem

Collectibles submissions arrive as phone photos, half-built spreadsheets, and round numbers. Values are guesses, the concentration and storage risk is invisible, and every back-and-forth delays the bind.

What your client brings instead

An Insurance Schedule & Risk Report: every card appraised from real comparable sales, a total scheduled value, a coverage-gap read, and a 0–1000 protection score — the same document, every time.

What’s in the report

Per-card schedule

Every slab itemized with cert, grade, and an appraised value from recent comparable sales across eBay, Heritage, Goldin, and PWCC — with a clean total.

Coverage-gap analysis

Stated insured value vs. current market value, flagged as fully scheduled or under-covered by a specific dollar amount — the number you need to write.

0–1000 protection score

A protection score across insurance, concentration, storage, liquidity, and provenance — a standardized signal of how exposed the collection is.

Concentration & liquidity

Top-holding exposure and how quickly the collection converts to cash — the risk dimensions a single appraised total hides.

Provenance & documentation

Which cards carry a verified grading cert, so claim documentation is established before a loss — not after.

Renewal-ready

Values refresh with the market, so each renewal starts from a current schedule instead of last year’s number.

Why it helps your desk

  • Faster, cleaner intake — a standardized schedule instead of photos and guesses.
  • See the coverage gap immediately, in dollars.
  • A consistent risk signal across every collectibles submission.
  • Fewer back-and-forths before bind and at renewal.
  • Better-documented claims, because provenance is captured up front.
  • A warm channel: collectors arrive from our coverage-gap calculator already knowing their gap — in dollars.

How it works

1

Client builds their collection

They add slabs by cert; Slabline values each from comparable sales and scores the collection.

2

They generate the report

A one-click Insurance Schedule & Risk Report — per-card values, totals, coverage gap, and protection score.

3

They share it with you

You receive a clean, current schedule ready for underwriting and renewal.

Partner with Slabline

We’re building simple mutual-referral relationships with brokers and collectibles insurers: your desk becomes the recommended specialist across our insurance guides and coverage-gap calculator, and your applicants arrive with a schedule your underwriters can work from. No integration required to start.

Slabline is not an insurance company, agent, broker, or certified appraiser. The Insurance Schedule & Risk Report is client-prepared documentation built from automated comparable-sales estimates — to support your underwriting, not replace it. Final values and coverage terms are determined by the carrier.
