About the data.

Raw prices

Every ungraded 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. 3,410 of the 3,471 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 932 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. The ladder runs the full PSA scale, 1 through 10, on 691 cards, with a monthly price history and the population report where the grader publishes one.

Two sources fill it and the card page says which you are looking at. Most rungs come from a marketplace price history that goes back to late 2020. The rest, 0 rungs across 0 cards, are ours: a median of what copies actually sold for, with the number of sales printed beside it. Those are rungs nobody else prices at all, mostly the played grades below a 7, and the count is there because a median of six sales and a median of six hundred are different claims.

Both rest on 0 completed sales across 0 cards, recorded by PSA itself and going back to 2017. All but 0 carry a photograph of the exact slab that sold and a link to the listing, so any price here can be checked against the sale behind it.

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.

The grading verdict is built on the population report rather than on the top price. Knowing a PSA 10 sells for ten times the ungraded 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

• Korean, Chinese and the European languages. English and Japanese only.
• Any assessment of your own copy. A condition ladder prices near mint through damaged, but it describes the market, not the card in your hand.
• 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.
