To begin selling baseball cards on eBay, you’ll first need to create an eBay seller account if you do not already have one. Go to the eBay website and click on “Register” or “Sign Up” to create your account. You will be prompted to enter basic contact and account information such as your name, address, email, and choose a password.

Once your account is created, you will need to gather the baseball cards you want to sell. Be sure to select cards that are in good condition without any creasing, damage, or stains. The better condition a card is in, the more valuable it will be to collectors. You may want to sort your cards by player, year, or set to make listing them on eBay easier.

When you’re ready to list your first card, log into your eBay seller account and click on “Sell” and then “Sell an item” from the main navigation menu. First, choose the appropriate selling format which for individual cards will usually be “Auction” with a starting price and no reserve or “Buy It Now” with a fixed price.

Next, you’ll need to upload photos of the front and back of the card to provide buyers with a clear view. Photos are arguably the most important part of selling online, so be sure they are well-lit and focused on important details. You can optionally provide additional angled photos if the condition warrants it.

In the title field, write an enticing but accurate title that includes the player name, year, set/issue and card number if applicable, condition, and any notable features or serial numbers. An example would be “2009 Topps Pete Rose #234 Near Mint!”. Keep titles under 80 characters if possible for better search engine optimization.

In the description, provide full details about the card such as any flaws, creases, centering issues etc. It’s also a good idea to mention the size and if it has been professionally graded. Links to completed listings of similar sold items can help sellers justify their price. Advice buyers to check your seller feedback and not to hesitate to contact with any other questions.

When setting a price, research recently sold “sold” listings on eBay for comparable cards to determine fair market value based on condition, player/set popularity. Also factor in any applicable sales tax. Auctions typically start low and increase over time, while Buy It Now prices should reflect what a ready buyer would pay now.

Once listed, promote your listing through suitable baseball card or player specific enthusiast groups and marketplaces. You can also promote to your own social media followers. Some top sellers offer combined shipping discounts or make automatic ‘Best Offer’ options available too.

As you receive orders, be sure to promptly pack cards securely between stiff cardboard or in protective plastic sleeves within a bubble mailed envelope. Clearly write ‘Do Not Bend’ on the outside and carefully hand over to your nearest Post Office. Ask the buyer to leave you positive feedback once received in good condition.

Monitor sold listings and be prepared to relist unsold items, perhaps with a lower price the second time. Develop a selling routine where you list fresh inventory at regular intervals like weekly to keep engagement high. Respond quickly to all buyer questions through the eBay Message Center for a smooth transaction and good seller ratings.

With persistence and by following these steps consistently, you can establish an impressive seller history and grow your secondary baseball card income over time on eBay. Research product trends to stay knowledgeable on the hottest players and sets at any given moment too. Most of all focus on excellent customer service and honest listings to keep buyers returning for more.
