Market
Market is the board of hot cards: the sports cards whose sold prices rose this week, measured from matched completed sales rather than asking prices or an index. Each card is ranked by how well the move is evidenced, not only by how big it is, and every row shows the sales behind it. It is free to read and needs no account.
Rising cards only. Cards that did not move are not on the board and falls are not charted, so a quiet week looks empty and a favourite player can correctly return nothing. The board measures the most liquid corner of the market, where a week holds enough sales to measure at all, and it does not claim to be the whole market.
The board can be narrowed to one sport, including baseball, basketball, football, hockey, soccer, golf, racing and wrestling, or to a trading card game such as Pokemon. A player lookup shows which of that player's cards are moving, measured the same way as the board.
This is a record of what sold, not a recommendation to buy or sell anything. Card values are estimates computed from public sold-listing data, not appraisals, offers, or investment advice.
Raw to Slab can also keep re-valuing the cards you own, and on a paid plan tell you when one of them moves. That half needs an account.
