About the data.

Raw prices

Every raw price is the TCGplayer market price, which is calculated from completed sales rather than active listings. We pull the full catalogue once a day, shortly after it publishes, and the site shows the number from that pull. 27,302 of the 27,807 cards we track carry a price; the rest have never traded often enough to have one.

Prices are for near mint, ungraded copies. Condition is the biggest single factor we do not model: a played copy of the same card trades well below the number shown.

Price history

We hold a daily snapshot back to Feb 8, 2024, which is 918 days of market history. Card charts run a three day median rather than the raw daily figure. On a card that trades a few times a month, the market price snaps to whatever printed that day and snaps straight back, so the raw line reads as a fault rather than as the single odd sale it was.

Graded prices

Graded numbers come from sales of slabbed copies, matched to the same card by its TCGplayer id. We show a ladder from Grade 7 up to PSA 10 on 21,475 cards, along with a monthly price history going back to late 2020 and, where it exists, the PSA population report.

One thing worth being blunt about, because most sites are not. A grade with no sales at that grade still gets a price, and that price is modelled from the grades that did sell rather than observed. Where that is the case we label it on the card page instead of letting it pass as a sale. It matters most at the ends of the ladder: plenty of cards have never had a single Grade 7 sale recorded.

The grading verdict is built on the population report rather than on the top price. Knowing a PSA 10 sells for ten times the raw card is close to useless if only one submission in two hundred comes back a 10, so every grade is weighted by how often the card actually lands on it.

What this does not cover

• Japanese and other non-English cards.
• Sealed product: boxes, packs and tins.
• Condition below near mint, and any per-copy assessment of your own card.
• Cards that have never sold often enough to carry a market price.

Corrections

If a price here looks wrong, it is usually one of two things: the card has several printings and the one you are looking at is not the one in your hand, or the card trades rarely enough that a single sale moved the market price. Both are visible on the card page itself, on the printing bars and the history chart.
