How to Check the Value of Baseball Cards Using WatchCount.com

Whether you’re sorting through a childhood shoebox or just picked up a collection at a garage sale, one of the first questions you’ll probably ask is: “How can I look up what my baseball cards are worth?” or “What’s the value of these baseball cards?”

Why Use WatchCount.com to Check Baseball Card Value?

How to Use WatchCount.com to Check Your Baseball Card’s Value

1. Search WatchCount’s Baseball Card Price Guide.
2. In the Keyword field, enter your card’s details.
   • If possible, identify it by year, card number, and player name. If it is graded, include the grading company and grade.
3. Set the Listing Type to Auctions Only.  Auctions are the best gauge of a card’s value.
4. Click the Search button above to run the sample search.
5. Analyze the results.  Focus on recently sold listings to see the actual prices similar baseball cards have sold for.  (If you do not have many results, adjust your Listing Type filter to All Items.)
   • Pay attention to key data points such as:
     • Sale price: What buyers actually paid.
     • Auction vs. Buy It Now: Was the card competitively bid on, or purchased outright?
     • Number of Bids: This tells you how competitive an auction was. A higher number of bids can indicate strong interest and demand for the card, helping validate its market value. The number of bids on an auction reflects how competitive the listing was. More bids can indicate stronger demand and suggest that the card’s value is being validated by multiple interested buyers.
     • Number of Unique Bidders: This reveals how many different people were actively trying to buy the card. Multiple unique bidders signal broad appeal, while just one or two may indicate a niche item. 
     • Sales velocity: How fast did it sell after being listed?
     • Condition and grading: Make sure you’re comparing cards with the same grade. A PSA 10 will sell for much more than a PSA 8, even for the same card. Also check for any grade qualifiers (like “OC” for off-center) that may affect the value. eBay has a basic guide to card condition for beginners. PSA has a much more detailed guide to grading standards.
     • Eye appeal: Even among cards with the same grade, some simply look better than others. Centering, color saturation, and print quality can influence how desirable a card is to collectors and affect its final sale price.  Carefully compare the eye appeal of your card to those that were recently sold and adjust the value up or down to as needed.
     • Watch Count: See how many people added the listing to their eBay Watch List. This provides insight into buyer interest and demand beyond just sale price or bidding activity.
