How to Read Card Price Data
Book values, market prices, sold comps — they all mean different things. This guide explains what each metric is, which to trust, and how to use them to make decisions.
In this guide
The three price sources (and what they actually mean)
Most pricing confusion comes from mixing up three fundamentally different data types.
- ▸Beckett Book Value: a subjective editorial price set by Beckett staff. Outdated quickly. NOT market price. Used primarily as a reference anchor by hobby veterans who grew up with it.
- ▸TCGPlayer Market Price: the trailing average of actual sales on TCGPlayer for Pokémon singles. Real data, ~24hr lag. The best single price reference for modern Pokémon.
- ▸eBay Sold Comps: the ground truth. Real transactions, searchable by exact card and grade. Most reliable for sports cards, vintage Pokémon, and graded copies.
Watch out
When someone says "it books for $X" — that's Beckett. When someone says "it sold for $X" — that's real. These numbers can differ by 50–300% for popular cards.
How to pull an eBay sold comp
Finding accurate comps takes one minute:
- ▸1. Go to eBay. Search the exact card: "[Year] [Player] [Set] [Card Number] [Grade if graded]"
- ▸2. On the left sidebar: check "Sold Items" under "Show Only"
- ▸3. Sort by: "Ending soonest" first (most recent), then expand to 90 days if too few results
- ▸4. Filter by: condition (graded vs raw), specific grade (PSA 9, PSA 10, etc.)
- ▸5. Look for the median of recent sales — ignore outliers on both ends
Grade multipliers
The same card in different grades can sell for wildly different amounts. These are general ranges — individual cards vary significantly.
- ▸PSA 10 vs PSA 9: typically 3–15× higher. Higher for vintage or low-pop cards.
- ▸PSA 9 vs PSA 8: typically 2–4× higher. This is often the biggest value jump.
- ▸PSA 8 vs PSA 7: typically 1.5–2× higher.
- ▸Raw NM vs PSA 8: raw typically 40–60% of PSA 8 price (varies by card liquidity).
Tip
Use our Grade Value Calculator to estimate the value across all grade tiers from a single known price.
When prices are misleading
Not all sales data is good data.
- ▸Single anomalous eBay sales: one record sale does not reset the market. Look at 5–10 sales.
- ▸Active listings: asking prices mean nothing — sellers list high, buyers decide the actual market.
- ▸Low-volume vintage: if fewer than 5 cards have sold in 90 days, pricing is illiquid. Any sale can be an outlier.
- ▸Auction house prices: Heritage, Goldin, and PWCC sales often exceed market due to auction premium and premium buyer pool. Adjust down ~10–20% for actual comparable market.
