The order book
Denominated in collectibles.
A price tells you one number. A book tells you what the market will actually hand you.

Anatomy of a card-denominated bid
01
The ask
A specific card: set, print, grade, slab. Not a category and not an average — the exact object on the table.
02
The bid
One card, several cards, or cards alongside cash, posted from what is already in a collection.
03
The spread
Where the two sides do not line up, the difference is closed — with another card, or with cash as the remainder.
Card to card.
No liquidation step, and no cash parked between the card you hold and the card you want.
