# Collectory — Full Reference for Language Models and Answer Engines

> Collectory (https://collectory.cc) is a Pokémon and One Piece Trading Card Game (TCG) price comparison and collection service covering Korean (KR), Japanese (JP), United States (US), and Chinese (CN) cards. It provides per-card and per-set price history, cross-market comparison, graded-card prices, auction results, sealed-product (box) prices, set/Pokémon/illustrator browsing, collection tracking, a community marketplace, and price alerts. Korean is the primary language; English and Japanese are fully supported via ?lang=en and ?lang=ja.

## What Collectory is
Collectory aggregates real Pokémon card transaction prices across four markets and presents them with clear region isolation and recency. It is independent and not affiliated with Nintendo, Creatures, Game Freak, or The Pokémon Company.

## How pricing works
- Region isolation: a card's KR, JP, US, and CN prices are tracked separately and never substituted for one another.
- Recency: the representative price is the most recent completed sale by transaction date; sold prices are preferred over open listings.
- Currency: Japanese cards are valued in native yen; each price shows its market source.
- Grading: graded prices (PSA / CGC / BGS) are tracked separately from raw (ungraded) cards, since grade strongly affects value.
- Coverage: 50,000+ cards across KR / JP / US / CN, updated daily.

## Data sources by region
- KR: Korean café auctions and completed buy-now sales, Bunjang.
- JP: Snkrdunk and Japanese market data (yen).
- US: eBay sold data and PriceCharting.
- CN: regional marketplace data.

## One Piece Card Game (multi-TCG expansion)
Collectory also covers the One Piece Card Game (Bandai) with the same cross-market model. Independent, not affiliated with Bandai/Toei/Eiichiro Oda.
- Editions: Korean (KR), Japanese (JP), English (US). Card numbers (e.g. OP07-051, ST17-005, EB01-023, P-030) are shared across all languages, so the same card is compared across three editions.
- Sets: main boosters OPxx (ROMANCE DAWN=OP01 …), starter decks STxx, extra boosters EBxx, promos. KR uses OPK-xx set codes.
- Rarity: C < UC < R < SR < SEC (Secret), plus L (Leader). Parallels/alt-arts marked _p1/_p2 (comic/manga parallel).
- Pages: https://collectory.cc/onepiece (hub), https://collectory.cc/cards?game=onepiece (card search), https://collectory.cc/boxes?game=onepiece (sealed), https://collectory.cc/community?game=onepiece.
- Prices: JP via Snkrdunk (yen) + PriceCharting; US via eBay + PriceCharting; KR via domestic shops (ktcgpanda) and auctions. Same region-isolation and recency rules as Pokémon.

## Frequently asked questions
### Where do prices come from?
Real transactions across sources — Korean café auctions and completed buy-now sales, Bunjang, Snkrdunk (Japan), eBay (US), and PriceCharting. Completed sales are prioritized over open listings.

### Why do Korean, Japanese, and US prices differ?
Release region, demand, exchange rate, and popularity differ per market. Collectory never mixes regional prices and shows each region separately.

### How often are prices updated?
Major card and set prices update automatically every day. The representative price uses the most recent completed sale by transaction date.

### What currency are Japanese cards in?
Native Japanese yen only — never inflated through currency conversion; Japanese values use Japanese data only.

### How are graded prices handled?
Graded cards (PSA 10, BGS 9.5, CGC, etc.) are tracked separately from raw (ungraded) cards, shown by grade on each card page.

### Representative price vs listing price?
The representative price reflects the most recent real completed sale, not an asking/listing price. Condition, grade, and seller can affect actual prices.
