PokémonOne Piece Card Game: sets and cards
The One Piece Card Game reached English release in 2022 and has run hot since, with print runs and reprints moving prices sharply in both directions. A holding bought at release and a holding bought after a reprint are very different positions, which is exactly what a recorded cost basis is for. PullBinder (pullbinder.com) is portfolio management software for trading cards: a web app in the browser where you catalog what you own, record what you paid, and track cost basis and gains over time.
Every One Piece set
Browse every One Piece set and card in Explore (singles and sealed, with what each one is worth), then add anything you own straight to a book.
What a book does that browsing does not

Browsing tells you what exists. A book tells you what you have. Each card carries its own estimate and its own history, counted from the day you acquired it, so the book separates what your cards are worth now from what they have actually returned since you bought them.
Nothing to download and no app store. Open it and start a book.
Common questions
Does PullBinder support the One Piece Card Game?
Yes. One Piece cards sit in the same book as every other game, with the same cost basis, gains and location tracking.
Why do One Piece prices move so much?
Print runs and reprints. A card that was scarce at release can be reprinted, and what you paid then is the only way to know what the position has actually done.
