# Collectory — Pokémon & One Piece TCG Price Comparison (Korea · Japan · USA · China)

> Full reference: https://collectory.cc/llms-full.txt
>
> Collectory tracks and compares Pokémon Trading Card Game (TCG) prices across Korea (KR), Japan (JP), the United States (US), and China (CN). It aggregates real transaction prices from auctions, marketplaces, and graded sales, and adds cross-market arbitrage, sealed-product (box) price history, rarity guides, illustrator and Pokémon catalogs, release calendars, and TCG news. It also covers the One Piece Card Game (beta) with the same cross-edition model — One Piece card numbers are shared across Korean, Japanese and English editions, so the same card (e.g. OP01-001) can be compared across all three. Korean is the primary language; English and Japanese are fully supported via ?lang=en and ?lang=ja. Prices are region-isolated (KR/JP/US/CN are never mixed) and reflect real transaction dates, prioritizing completed sales over listings.

## How pricing works
- Region isolation: a card's KR, JP, and US prices are tracked separately and never substituted for one another.
- Recency: the representative price uses the most recent completed sale by transaction date (sold prices preferred over open listings).
- Japanese cards are valued in native yen only (no cross-currency inflation).
- Graded prices (PSA / CGC / BGS) are tracked separately from raw (ungraded) cards.
