A sports card price guide built from what cards actually sold for

A listing price is what a seller hopes to get. A sold price is what a buyer paid. On any marketplace the two routinely differ by 30 to 50 percent. Unsold listings sit at hopeful prices for months, while the sales that clear happen lower and faster. Every price SnapCard shows comes from a completed transaction, which is why it can be lower than an active search suggests.

A card that trades twice a year has no meaningful asking price, only the two results that closed. The guide shows those sales with their dates, so you can judge how thin the data is.

Search for a 2018 Panini Prizm Luka Doncic rookie and the results run from under $50 to over $1,000 as of 2026, all for one card number. Nothing is wrong with the data. The card exists as a base version, a dozen parallels and every grade from raw to PSA 10. Each combination is its own market, which a single book value cannot describe.

• Grade: a PSA 10 of a modern rookie commonly brings 3 to 8 times the raw price as of 2026, while a PSA 9 often adds little
• Parallel: base, refractor, numbered and one-of-one versions share a card number and nothing else
• Sale format: an auction finds the market price on the day; a fixed-price sale shows what one patient seller accepted
• Timing: a rookie can move 40 percent in a month around a playoff run, an injury or a trade
• Platform: a major auction house often brings more than a marketplace for the same card, because the bidders are different

SnapCard records the platform behind every sale, because the source changes how you should read the number. Five sources feed the guide: eBay, Goldin, Heritage Auctions, PWCC and Pristine Auction. A $300 hammer price and a $300 Buy It Now are not the same evidence.

Sales that closed through an accepted offer on eBay often display the listed price rather than the amount paid. That is one more reason a single fixed-price result should never anchor a valuation.

A comp, short for comparable sale, is a recent sale of the same card in the same condition. Three comps from the last 30 days are worth more than thirty from last year. In the average, low and high SnapCard shows, the low is usually a damaged copy or a badly timed auction. The high is usually a bidding war. The average is where most sales land, so sell near the average and buy near the low.

The trend label is the piece a book value cannot give you. Rising means recent sales are closing above earlier ones, Falling means the opposite, and Stable means the card trades in a narrow band. A stable card with 20 or more comps is the easiest card in the hobby to price.
