A binder full of Evolving Skies chase, Base Set classics, and modern SIRs is hard to value from memory. Spreadsheets go stale; sold comps on one card do not tell you what the whole collection is worth this week.
Why Pokémon collection value drifts
- +Printing and set matter — Shadowless vs Unlimited, or the wrong SIR art, can swing hundreds.
- +PSA 10 premiums move separately from raw floors.
- +Sealed product and singles behave like different markets.
- +One viral reprint or set drop can reprice a whole binder overnight.
Track owned Pokémon cards on GrailHawk
Open Portfolio and add each card you own — or multi-select from /cards or /pokemon. We store the marketplace query and optional grade, refresh a conservative live floor, and snapshot total value so you can see history, not just today’s ask.
Confirm set, number, and treatment on the card page. A Moonbreon logged as a common Umbreon will invent fake gains.
Hunt on Wishlist, value on Portfolio
Keep price alerts for cards you still want. When you buy, use I own this or Add to portfolio from the alert email so the watch pauses and the holding starts counting toward collection value.
