Pokémon Card Collector Guides

Straight answers to the questions Pokémon card collectors keep asking: what a collection is worth, whether to grade, how to buy, sell, ship, store, and insure cards, and what to do about taxes or an inherited collection. Every guide starts with the short answer, then the reasoning, and none of it is appraisal, pricing, or investment advice. The guides come from Portfolio AI Corp, the team behind Portfolio, the iOS app that keeps your cards, sealed product, and everything else you own in one verified asset registry, with Port, its AI assistant, built in.

Value & pricing

What your cards are worth, and why the numbers disagree.

  • How Much Is My Card Collection Worth?: Your collection is worth what recent sold comps support for the exact cards you hold—in the condition you actually have—minus fees, shipping, and time to sell.

  • Why Do Card Pricing Apps Disagree?: Pricing apps disagree because they often measure different things—asking vs sold, raw vs graded, different condition bands, stale feeds, and fees that never hit the sticker.

  • Are Japanese Pokémon Cards Worth Less Than English?: Usually, yes, for the same card. Here's why the English copy tends to sell higher, the exceptions where Japanese wins, and how to price each one.

Condition & authenticity

Check what you actually have before you price, grade, or sell it.

Grading

Whether to slab a card, with whom, and when to open one.

  • Should I Grade My Pokémon Cards?: Grade only when the slab premium clears fees, risk, and time. A clear triage for inherited collections, raw vs PSA, and when to wait.

  • Should I Grade with PSA or CGC?: Sell soon? Lean PSA. PC, cost, or look? Often CGC. Compare all-in fees to grade premium—and verify live tiers before you submit.

  • Should I Crack a Graded Pokémon Card?: Crack a slab only for a PC binder you will keep—voids grade, cert, and guarantee. Prefer mid grades near raw comps; keep high-value keepers slabbed.

Buying & sealed product

Singles, packs, slabs, and sealed: what to buy and what to open.

Selling & shipping

Where to sell, how to split a collection, and how to get it there intact.

Storage, records & insurance

Keep cards safe, documented, and covered.

Taxes & inherited collections

The paperwork side of selling and receiving a collection.
