For card shops & dealers

Your inventory, valued well enough to insure

A cited appraisal schedule your carrier will accept, comp values at every grade on every slab you hold, and grading decisions costed before you ship the submission.

The renewal problem

Your carrier wants a schedule. What you have is a spreadsheet of round numbers you updated at some point last year, a display case that has turned over twice since, and no citation behind any figure. At claim time that is the document that decides what you get paid.

What you hand them instead

An Insurance Schedule & Risk Report: every slab appraised from real comparable sales with the sale cited, a total scheduled value, and a storage and concentration read — regenerated whenever the inventory changes, not once a year.

A schedule with citations

Every appraised value names the sale behind it — date, price, grade and venue. A number a carrier can check is worth more at claim time than a number you assert.

Priced at every grade

A value ladder across PSA, BGS, SGC and CGC on over a million cards, so a PSA 8 in the case is not priced off a PSA 10 multiple.

Grade before you submit

Pre-Grade estimates what a raw card comes back as and what it would be worth slabbed, against current grading fees. Submission economics before you pay the fee, not after.

Population and gem rate

How many exist at each grade and how often that card comes back a 10 — the difference between a submission worth making and a $60 lesson.

Bulk in, not card by card

Import an existing inventory sheet — Card Ladder, Market Movers, Mascot, eBay or Whatnot exports all parse. You should not be retyping a case you already tracked.

Storage risk, scored

Where inventory sits and how it is handled, scored 0–1000 with the gaps named. Carriers price risk they can see; so should you.

We are not a marketplace

Slabline does not buy, sell, consign or take a cut of your inventory, and we do not compete with your shop for it. We value it, document it and tell you when the market moves against something you are holding. When you decide to sell, you sell wherever you already sell.
