Build a fair Pokémon card price range by collecting several recent sold prices for closely matched copies, then report the low, high, and median. A fair range reflects what buyers actually paid, not what sellers hope to receive. "Comparable sales," or comps, must represent the same card, printing, condition, and grading status. Loose matches can produce a precise-looking range that is fundamentally misleading.

Define the exact card before searching
Identify the card by name, set, card number, edition or printing, language, and special features such as holofoil or reverse holofoil. eBay's trading-card guidance treats the franchise, card name, printing, features, grading company, and numeric grade as core listing identifiers in its CCG selling guidance. Do not combine normal, reverse-holo, promotional, foreign-language, and differently conditioned copies.
TCGplayer states that its Market price and Most Recent Sale follow the selected printing and condition filters in its price-point documentation. Separate raw cards from graded cards. For graded copies, match both the grading company and numeric grade. A PSA 9, for example, should not share a comp group with a raw card, PSA 10, or another company's grade.
Gather recent sold prices
Search sold or completed transactions rather than active listings. An unsold asking price shows what a seller wants; eBay recommends Completed Listings for seeing what similar items actually sold for in its pricing guidance.
Start with the most recent sales and record each genuinely comparable result. Capture enough detail to review the match later: eBay's basic completed-listings search covers recently ended sales from the prior 90 days. Its Product Research tool can examine a chosen interval from one day to one year within three years and records the actual accepted price for Best Offer transactions, according to eBay's Product Research overview.

Clean the comparable-sales group
Remove a sale when the listing reveals that it belongs to a different card group. Common reasons include the wrong printing, language, foil treatment, condition, grading company, or grade. For raw cards, compare the visible condition carefully. One serious flaw can separate a card from cleaner-looking copies, even when the remaining surfaces appear similar.
Photos and descriptions therefore matter more than a broad label alone. Do not delete a high or low result merely because it makes the range untidy. First check for a concrete mismatch. If the sale is genuinely comparable, keep it and let the wider range show the card's observed price variation.
Calculate and present the range
Sort the matched sold prices from lowest to highest. Use the first and last values as the observed range, then calculate the median—the middle value after sorting—as the group's center. Suppose five matched sales were $72, $76, $79, $81, and $95.
The observed range would be $72–$95, and the median would be $79. This format shows both the full spread and the price around which the sample is centered. If two values share the middle position, average them to find the median. For $72, $76, $80, and $84, the range is $72–$84 and the median is $78.
Know when the evidence is too thin
One last sale cannot establish a range. With only one or two matched transactions, label the result as limited evidence and consider widening the search period before loosening the card criteria. A wide spread may reflect unstable pricing, condition differences that listings fail to describe clearly, or simply a small sample.
Report the number and dates of the comps so readers can judge how much weight the range deserves. Authentication does not turn a raw card into a graded card. Even when a marketplace authenticates a transaction, an ungraded sale still should not be compared as though it carried a PSA, BGS, CGC, or SGC grade.
