Everything in the Ledger
Market intelligence for One Piece collectors: verdicts with a public track record, three markets on every card, and tools that point the playbook at your own collection. All of it free until August 20.
Plug the Ledger into your AITCG first
The first backtested TCG verdicts with a native AI connector (MCP), self-serve in one click. Add us to Claude or ChatGPT and ask the One Piece market directly: live prices, verdicts, populations, and sold volume, from our database. Included with the Captain tier.
See it →Daily verdicts on 6,500+ products
Every card, box, and tin gets a stamp every day: ACCUMULATE, HOLD, SELL WATCH, or REBOUND WATCH. Backtested against 2.5 years of real prices before a single call went live.
See it →A track record nobody can edit
Every call is logged the day it fires and graded automatically at 4 and 8 weeks. We cannot delete our misses. If the playbook stops working, the scoreboard says so first.
See it →Three markets, one card
US market prices and sold comps, European near-mint prices, and live Japanese dealer quotes with buyback. Flip any card page between the English and Japanese printing.
Ledger Lens on your collection
Point the playbook at your own cards: see which holdings are on buy calls, run keep-or-sell scenarios on the warnings, and catch cards running hot enough to take profit.
See it →Collection value, backdated
Add your binder and instantly see its value curve over the past year. No waiting for history to build, because we already recorded it. Snapshotted daily from then on.
See it →Scarcity Score
How hard a card really is to find, from PSA, CGC, and BGS graded populations (English and Japanese prints scored separately) plus live market supply. Updated daily.
Sold sales archive
Real completed sales with links to the actual listings, searchable across the whole game. Prices stay in our record forever; verify any number we publish.
See it →Radar and watchlists
The daily short-list of movers and setups worth attention, plus watchlist alerts so the cards you care about tell you when something changes.
See it →Strategy fit: Flip, Hold, Grade
Three scores on every card answering which kind of collector it suits. A terrible flip can be a great hold, and the scores will say exactly that.

A fresh article every day from the live data: movers, stories, and what we are watching. Written from the numbers, never from hype.
