Collectory is a service for comparing Pokémon card prices across the Korea, Japan, US, and China markets.
Collectory compares Pokémon card prices across Korea, Japan, the US, and China in one place. It gathers scattered transaction data to show per-card and per-set representative values with price history, making cross-region price gaps easy to see at a glance.
Collectory's prices are based on real transactions, not open listings. We collect actual sale prices by source — Korean café auction results and completed buy-now sales, Bunjang, Snkrdunk (Japan), eBay (US), and PriceCharting. Completed sales are prioritized, and regional prices are never mixed but shown separately. Japanese cards are valued only in native yen and are not inflated through currency conversion. The representative price is based on the most recent completed sale by transaction date.
Search a card to compare prices across regions, and view graded (PSA/CGC/BGS) prices separately from ungraded cards. Once logged in, you can add the cards you own as a collection to track value and daily changes, and you can also see prices and history for sealed products like booster boxes, bundles, and tins. News and a release calendar help you keep track of upcoming sets.
Collectory is available in Korean, English, and Japanese. Switching the language also adjusts the default region shown (Korean → Korea, Japanese → Japan, English → US).
