A board of the cards whose sold prices moved up this week, built from matched completed sales rather than asking prices or an index. It is free to read, and reading it needs no account.
What it measures, stated plainly: the most liquid corner of the market, where a week holds enough sales to measure at all. It is not the whole market, and we do not claim it is. Cards that did not rise are not on it, and falls are not charted, so searching a favourite player in a quiet week correctly returns nothing.
The half worth paying for is the useful half. Raw to Slab.ai can keep re-valuing the cards you already own and tell you when one of yours moves, and it can watch cards you do not own yet and alert you when their sold price changes. Discovery is a commodity. Knowing your own shelf just moved is not.
This is a record of what sold, not a recommendation to buy anything. Card values are estimates computed from public sold-listing data, not appraisals, offers, or investment advice.
