Pokemon Card Pricing Methodology
Updated October 20, 2026
Every price you see on Double Holo, raw or graded, is built from real sales and real order-book activity, not a guess. This page explains exactly where those numbers come from, how conditions and grades are matched, when a price is an estimate, and when Double Holo shows no price at all rather than make one up.
As of October 2026, Double Holo computes card market prices from completed sales, with outlier and low-confidence sales excluded, and shows live bid and ask prices separately.
Prices from Double Holo completed sales, as of October 20, 2026.
Where do Double Holo's prices come from?
A card's market price is built from completed sales, not asking prices. A graded card's market price comes from trusted completed eBay sales in that exact grade. A raw near mint price is a daily market price from an outside marketplace. Live bid and ask prices from the order book are shown alongside the market price, but as their own clearly labeled numbers, never blended into it.
Not every sale counts. Before a sale is used in a price, it has to pass a confidence check: outlier sales, low-confidence sales, sales flagged as invalid, and negotiated best-offer deals are all excluded. A card's price is built only from sales that clear that bar.
Except where a value is explicitly labeled as an estimate, a graded market price is computed from completed sales, not from estimates.
How do raw card prices work?
Raw (ungraded) prices are anchored to a near mint (NM) baseline, the condition labeled "Raw NM" across Double Holo, and that baseline refreshes daily. It is a market price synced from an outside marketplace, so the graded steps below do not apply to it. A card in a lower condition, played corners, whitening, surface wear, is worth less than a near mint copy of the same printing.
Grading changes the picture entirely, since it replaces a visual condition estimate with a verified, sealed grade. See how much your Pokemon cards are worth to compare a specific card's raw price against its graded prices side by side.
How do graded card prices work?
A graded price is always tied to one specific grading company and grade, for example PSA 10, never blended across grades or averaged with a different company's scale. Here is the pipeline, in order:
- Pull up to the 5 most recent trusted sales for that exact card, in that exact grading company and grade, sold within the last 365 days.
- Set aside any sale that sits more than 25% off the group's middle price, where recent sales count for more in finding that middle, so the latest sales set the reference point. That outlier rejection keeps a single bad-faith or miskeyed sale from skewing the price. The newest sale is never set aside this way unless it is 5 times or more (or a fifth or less) of that middle price. One fresh sale at 5 times or more (or a fifth or less) of the typical price of the others cannot reset the price on its own. This check only runs with at least 4 sales, and it is kept only if at least 3 sales survive it. If fewer than 3 sales are within 25% of that middle and it sits 5 times or more (or a fifth or less) from the plain middle of the same sales, the check is run around the plain middle instead, and the newest sale gets no exemption. On vintage cards (Sun & Moon era and older) only unusually low sales are set aside, so a genuine high sale still counts.
- Average what is left, weighting more recent sales more heavily. The weight halves about every 10 days, so a sale from three weeks ago counts about a fifth as much as one from today.
- If fewer than 2 sales survive that process, it is too thin to trust on its own, so Double Holo falls back to a daily pricing snapshot for that grade and marks the result as an estimate.
- If there is exactly one trusted sale and no snapshot either, that single sale is used as a last resort, also marked as an estimate.
- If none of the above produce a number, Double Holo shows no price. It does not guess.
Where some surfaces work differently
A few surfaces deliberately skip part of the pipeline above. Price alerts and seller auto-pricing do not fall back to a daily snapshot, so a card with fewer than 2 trusted sales is left out rather than estimated. The partner data feed reports the single most recent trusted sale instead of the weighted average. And the raw-condition estimates a scan gives for an ungraded card are estimates, not graded market prices.

How often do prices update?
Double Holo's catalog refreshes daily, and new trusted sales are brought into a graded card's comp as part of that refresh. A price you see today can move by tomorrow simply because a fresh sale changed the recency-weighted average behind it. A card that is showing an estimate keeps it until it has at least 2 trusted sales in that grade.
When will you see an estimate instead of a market price?
Thinly traded cards do not always have enough sales history to support a full weighted comp. When a card has fewer than 2 trusted sales in its grade, Double Holo labels the price an estimate rather than presenting it as an equal match for a well-supported, multi-sale comp.
An estimate comes from one of two places: a daily pricing snapshot for that grade, or, if even that is missing, the single trusted sale on record. Either way, the label tells you the number is thinner than a full comp, not that it is wrong.
What Double Holo does not do
- No asking prices dressed up as sales. Every market price is built from completed sales, not asking prices. An active listing or bid is shown as exactly that, not folded into a card's sale-based price.
- No fabricated numbers when data is thin. When there is not enough sale history for a real price, Double Holo shows an honest "no data" state. It never substitutes a hardcoded multiplier or a made-up number just to avoid showing nothing.
- No blending across grades. A market price is only meaningful for a specific grading company and grade. Double Holo never shows a single price that quietly spans multiple grades or conditions.
- No analytical output relabeled as the price. Price forecasts, sentiment scores, and the ROI percentage and profit in Grading ROI are useful numbers, but they are not the market price. They keep their own names so they're never mistaken for a sale-backed comp.

Frequently asked questions
Where do Double Holo's prices come from?
Completed sales. A graded card's market price is built from trusted completed eBay sales in that exact grade, and a raw near mint price is a daily market price from an outside marketplace. Live bid and ask prices are shown too, but as separate, clearly labeled numbers, never blended into the sale-based market price.
What counts as a "market price" on Double Holo?
For a graded card, it is a recency-weighted average of up to 5 trusted sales in that exact grading company and grade, within the past year, with outlier sales dropped. Raw prices use a near mint (NM) baseline that refreshes daily.
Why does a price show an "est." label?
An "est." label means the price is an estimate rather than a sale-backed comp: fewer than 2 trusted sales exist, so Double Holo used a daily pricing snapshot or a single recorded sale instead of a weighted average.
Why is there no price shown for some cards?
When there are not enough trusted sales and no snapshot price to fall back on, Double Holo shows an honest "no data" state instead of guessing. A missing price is more accurate than a fabricated one.
How often do prices update?
Double Holo's catalog refreshes daily, and new trusted sales are brought into a graded card's comp as part of that refresh. A price shown today can move by tomorrow as fresh sales arrive.
Are Grading ROI or forecast numbers the same as the market price?
No. Price forecasts, sentiment scores, and the ROI percentage and profit in Grading ROI are separate analytical outputs, labeled for what they are. They are never presented as the card's market price. The per-grade prices that Grading ROI starts from are the same graded market prices shown on the card page.
