Quick answer
Quick answer
Identify the exact card, gather several relevant recent sales, remove mismatches and obvious outliers, adjust for condition and timing, then agree on a working value. Prepare screenshots or an inventory export for key cards because venue service can fail when the room gets busy.
The short version
- Exact card identification comes before price search.
- Use a cluster of relevant sales, not one convenient result.
- A comp is evidence for a decision, not a rule that replaces condition and liquidity.
What is the fastest reliable comp workflow?
Search year, set, player or character, card number, parallel, grade, and serial number where relevant. Compare listing photos and cert information. Then gather multiple sold results close enough in time and condition to describe the current market.
If the results spread widely, look for a cause: auction timing, accepted offer, poor title, card condition, wrong variation, low-feedback seller, or a market move after the sale.
How should accepted offers and outliers be handled?
A crossed-out price does not show the actual accepted amount. Use a tool that reveals accepted offers when available and verify that the result matches the card. Do not average an obvious mismatch into the value simply because it appears in the results.
- Prefer recent, exact, normal-condition sales.
- Use auctions and fixed-price sales together when both are representative.
- Note whether shipping is included in the displayed price.
- Widen the range when sales are old or sparse.
What should be prepared offline?
Export the key inventory list with cost basis, current asking price, and the date of the last comp. Save screenshots for high-value or thinly traded cards. A stale offline comp should trigger a fresh check when service returns, not become permanent evidence.
Use one device for customer-facing comping and keep account notifications private. Avoid exposing customer messages, purchase history, or unrelated tabs while showing a result.

Quick answers
Frequently asked questions
How many sold comps are enough?
Use enough relevant results to see a range and pattern. Three strong recent matches can be more useful than twenty mixed variations, conditions, and dates.
Are eBay sold listings the market price?
They are important evidence, but each sale has context. Compare exact items, accepted offers, shipping, condition, timing, and other active sales channels before deciding.
What if a card has no recent comps?
Use older exact sales, related grades or variations, auction-house records, and current demand to create a wider range. State the uncertainty and avoid pretending one distant comparison is exact.
