The first step is to select the baseball cards you want to sell. Go through your collection and pick out cards of hall of fame players, rookie cards, rare inserts, and cards of current star players. Avoid damaged, common, or worthless cards as they will be very difficult to sell. Once you’ve selected the cards, it’s time to get them ready to photograph and list. Ensure the cards are in mint condition by carefully placing them in soft sleeve protectors. Gently wipe down any surfaces to remove fingerprints or dirt.

Next, you’ll need to take photos of the cards. Use a neutral background and make sure the images are high quality and in focus. For rare or valuable cards, take multiple photos showing the front and back of the card as well as close-ups of any identifying marks. Invest in a lightbox or stand to properly display the cards and reduce shadows. When taking photos, hold the card by the edges and corners to avoid fingerprints or residue.

Now it’s time to list the cards on eBay. Start by selecting the appropriate listing category such as “Baseball Cards”, then choose the specific subcategory like “Rookie Cards” or “Hall of Famers.” In the title, include the player’s name, year, set, and card number. For example: “1998 Mark McGwire Topps Rookie #383.” When writing the description, provide as many identifying details as possible such as the brand, set, number in set, condition details, and anything that makes the card unique.

Describe the condition of the card using industry standard terms such as “mint”, “near mint”, “excellent”, “very good” etc. and back it up by including close-up photos. Note any flaws clearly. It’s important potential buyers understand the condition as this greatly impacts the value. Also include the current market value for reference and recently sold listings of comparable cards to justify your price. In the item specifics, input the brand, year, player, and any other applicable attributes.

Make sure to properly categorize the listing into the appropriate collecting niche since base rookie cards sell for more than update rookies. Set an appropriate starting price based on condition, recent sales and market value. The standard eBay listing formats of auction or “Buy It Now” are generally best. For rare cards, you may want to offer it with the “Best Offer” option enabled. The standard duration of 10 days is a good starting point.

In the payment section, only accept immediate payment methods like PayPal to avoid unpaid item cases. Clearly state in the description that the card will be shipped in a sleeve and toploader within 1 business day of payment in a penny sleeve inside a team bag. Proper packaging and fast shipping is key to a positive buyer experience. Also note you are happy to combine shipping on multiple card purchases.

Don’t forget to clearly photograph your user ID next to the cards as proof of possession. This provides buyers reassurance. Promote your listing on trading card forums, groups on social media and via eBay’s “Promote” button to get more views and increase your chances of a sale. Be sure to closely monitor the auction and promptly answer any buyer questions.

If the item doesn’t sell or you receive an offer you’re willing to accept before the end of the auction, you can always relist the card with a lower starting price or accept the best offer. In the case of a successful sale, promptly package and ship the card with tracking. Provide the buyer with the tracking number for peace of mind. Upon delivery, leave positive feedback and thank the buyer for their purchase. Repeat these steps to steadily grow your eBay sports card selling business. Always strive for excellence in photography, description, packaging and communication to develop trusted seller status over time. With patience and diligence, you can potentially turn your baseball card collection into a profitable reselling endeavor.
