Is My Graded Card Collection Underinsured? How to Tell

Underinsurance is the most common — and most expensive — mistake collectors make. You insured the collection at one value, the market ran, and now a total loss would pay out a fraction of what your slabs are actually worth. Here is how to know if that is you.

Check your coverage gap — free 60-second calculatorEnter what your collection is worth and what actually names your cards on a policy. See the dollar amount you’d be eating if the worst happened — and what closing it typically costs.

The two ways you end up underinsured

First: you never scheduled the collection at all, so it falls under your homeowners policy’s low collectibles sub-limit (often $1,000–$2,500 total). Second — and sneakier: you scheduled it years ago at a value that is now stale. A collection appraised before a market run-up can be underinsured by half or more without you touching a card.

How to check in five minutes

Pull your current declared coverage amount, then get a fresh, comp-based total of what the collection is worth today. If the gap is more than a few percent, you are exposed — a loss would be capped at the lower, outdated number.

Slabline does this automatically: it re-values every slab from real comparable sales and flags the drift between your covered value and current value, so the gap is never a surprise.

Closing the gap

Take a current, itemized valuation to your insurer and update the scheduled amount. The right number is today’s market value, documented per card with cert numbers and comps — exactly what a broker-ready Schedule & Risk Report contains.

Slabline is not an insurer or broker; it produces the documentation you hand to your own licensed carrier so coverage keeps pace with the market.

Frequently asked questions

How do I know if my card collection is underinsured?

Compare the collection’s current market value against the amount actually scheduled on your policy. The difference is your uncovered exposure. Collections that appreciated since the last appraisal are the most commonly underinsured.

How often should a card collection be re-appraised for insurance?

At least annually, and after any significant market move or major acquisition. Card values can drift 15–30% in a year, and a claim pays against the scheduled value — not what the cards are worth on the day of the loss.
