Trading Card Collections: Protecting Pokémon and Magic Cards from Humidity and Mold Exclusions

You’ve spent your adult life reclaiming your childhood. Your spare bedroom is a climate-controlled shrine to your collection. You have pristine, PSA-10 graded Pokémon holographics and a binder full of dual lands for Magic: The Gathering. The collection is easily worth $40,000.

While you are away on a two-week vacation, your central air conditioning unit dies. It’s August in Florida. The humidity in your house spikes to 90%. When you return, the climate-controlled sanctuary smells like a wet basement. You open your display cases to find that condensation has permeated the slabs, and black mold is growing on the edges of your raw cards. Your entire investment is ruined. You call your homeowners insurance, assuming your $100,000 personal property limit will save you.

The Brutal Truth: Why Standard Policies Deny This Claim

You are about to be hit by two of the most devastating exclusions in the insurance industry: the Mold and Fungi Exclusion and the Collectibles Sub-Limit.

Standard HO-3 Policies almost universally exclude damage caused by mold, mildew, and prolonged humidity. Unless the mold is the direct result of a sudden and accidental covered peril (like a burst pipe that you mitigated immediately), the carrier will deny the claim entirely, citing your failure to maintain the environment.

But even if a covered peril—like a house fire—destroyed the cards, you’d still be in trouble. Read your policy’s Special Limits of Liability. Almost all standard policies cap the payout for “paper records, manuscripts, and collectible trading cards” at a miserable $200 to $500 total. The insurance company doesn’t care about the Charizard’s PSA population report; they view it as printed cardboard with a maximum liability of $200.

How to Actually Protect Yourself (The Fix)

You cannot insure a highly liquid, volatile investment asset with a generic residential policy. You need specialized collectibles coverage.

  • Purchase a Standalone Collectibles Policy: Bypass standard homeowners insurance entirely. Contact specialty insurers like Collectibles Insurance Services (CIS) or MiniCo. They offer policies specifically underwritten for graded cards, comics, and memorabilia.
  • Insure for “Agreed Value”: Standard policies pay Actual Cash Value. Collectible policies pay Agreed Value. You and the insurer agree on the collection’s worth upfront based on PSA/BGS gradings and recent auction data, so there is no depreciation argument after a loss.
  • Install Active Climate Monitoring: Don’t just rely on standard AC. Install a smart hygrometer that alerts your phone the second humidity crosses 60%, allowing you to intervene before mold takes hold.

The Claims Adjuster’s Secret

If you try to file a massive theft or fire claim for raw (ungraded) cards, we will fight you on the valuation every step of the way. You cannot claim a raw card is in “Mint” condition just because you say so. Adjusters will automatically downgrade the assumed condition of raw cards to “Moderately Played” or worse when calculating the payout. If you want top dollar, get the cards professionally graded and cataloged.

The Verdict (TL;DR)

The Risk Level: Extremely High (Cardboard is highly susceptible to uninsurable environmental damage). The Solution: Secure a standalone Collectibles Policy with Agreed Value coverage. Estimated Cost: Roughly $250 to $400 annually for a $40,000 collection.

A $200 sub-limit won’t even cover the plastic slabs; stop trusting your life’s collection to a standard homeowners policy.
