The fastest way to know what a card is worth before a show is to look at what the same card actually sold for on eBay recently. Not what it's listed for. Use eBay's Sold Items filter for the last 90 days, or eBay's free Product Research tool for up to 3 years of sales (eBay Product Research). Then decide your price, your floor, and what you'd take in trade.
| Tool | How to get there | What it shows |
|---|---|---|
| Sold Items filter | Search the card on eBay, then check 'Sold Items' in the search filters. | Listings that sold in the last 90 days (per eBay). eBay says Product Research, unlike this view, shows the actual price when a Best Offer was accepted. |
| Product Research (formerly Terapeak) | Seller Hub → Research tab → Product research. Free for sellers with Seller Hub access. | Up to 3 years of eBay sales: average price, price range, average shipping, sell-through rate, and the actual sold price even when a Best Offer was accepted (eBay). |
Dealers at a show are buying to resell, often on eBay, so they work back from the sold price. For sports trading cards, eBay's final value fee is 13.25% of the total sale up to $7,500 (2.35% on the part above), plus $0.40 per order over $10 ($0.30 for $10 or less). The total includes shipping and sales tax the buyer pays (eBay selling fees).
Example (our math): a card with a $50 sold comp and $4.95 shipping has a fee of about 13.25% x $54.95 + $0.40 = $7.68 before sales tax, so the seller keeps roughly $42 before postage and supplies. That's why a dealer's cash offer is often well below the eBay comp. Decide ahead of time:
