Compare cards and listings

Two to four exact cards or live listings, side by side. Every figure says what it rests on — a confirmed sale, a model estimate, a count, or nothing at all — and a row whose sides are not the same kind of evidence is shown, labelled, and never ranked.

A card slug or a pasted card-page link names a catalog identity; a pasted listing link or a bare number names one live listing. Add @psa10 to a card to value it in that slab's market instead of raw — raw and each slab are separate markets, and the table says so when they differ.

Name at least 2 subjects to see the comparison. Up to 4 fit.

How to read this table

Every cell says what it rests on. A confirmed figure is built from witnessed sales of that exact identity. A modeled figure is arithmetic over assumptions or adjacent evidence — a real number, and not the same kind of thing. Putting one beside the other unlabelled is the single way a comparison surface does damage, so the two are never presented as equivalent and no row that mixes them is ranked.

“Not known” is not zero. Where we hold nothing the cell says so in words and gives the reason, because an empty box and a dash both read as a measured value of none. Population is the sharpest case: no dated registry observation means we did not look, which is not a population of none — see raw vs slab for what we do and do not hold about graded copies.

Prices are shown and never scored. A more expensive card is not a worse card, and a cheaper one is not a better buy. Only three rows carry a direction — discount, liquidity and sales frequency — because each is one measurement of ours on one axis where more is plainly better. Collector significance is deliberately not ranked: an unrated card is a gap in our curation, and highlighting the rated one would punish whichever card we happen to know less about.

A catalog identity is not a listing. A card has no ask of its own, so it has no action, no target and no hard max — those rows read not applicable rather than borrowing a number from the cheapest copy currently listed. The cheapest live copy and one seller's ask are two different facts, and the table keeps them apart even though both are dollars.
