Whether you have a collection of vintage baseball cards sitting in your attic or you’re looking to offload duplicates from recent packs, selling your cards is a great way to earn some extra cash. With so many options online, it can be difficult to determine the best sites to sell baseball cards. This comprehensive guide will explore some of the top marketplaces and platforms for selling baseball cards and help you choose which one is the right fit based on your needs.
eBay – As the largest online marketplace, eBay is one of the best-known and most popular sites for selling baseball cards. With millions of active buyers, you have a very good chance of finding interested bidders on almost any card on eBay. Some key advantages to selling on eBay include the huge audience, ability to set your own prices or auction cards off, and option to accept offers. EBay also takes a final value fee of 10% on each sale. Shipping is also the responsibility of the seller. Still, the massive traffic makes eBay a top choice for moving cards quickly at potentially higher prices.
COMC (Cardboard Connection) – Founded in 2000, COMC (formerly known as Collectors Universe) has grown to be one of the most trusted and efficient online marketplaces for sports cards, coins, and other collectibles. Sellers can send their cards to COMC’s warehouse to be professionally photographed, graded if desired, and listed for sale. This takes the hassle out of photographing and describing listings for the seller. COMC charges monthly or annual membership fees for storage and listing services but only takes 8% of the final sale price. They also handle all shipping. This full-service model makes COMC a great option for larger collections.
Sportlots – In business since the 1990s, Sportlots is another major online destination focused specifically on trading cards, memorabilia, and other sports collectibles. Like COMC, Sportlots provides professional photography and description services. They do not currently offer third-party grading. Sellers can choose to keep their items stored at Sportlots or ship items directly to buyers. Sportlots takes a 10% commission on completed sales. Shipping is the responsibility of the buyer or seller based on the listing details. Overall, Sportlots is a reliable marketplace with very competitive fees.
Facebook Marketplace – While not a dedicated cards marketplace like eBay or COMC, Facebook’s online classifieds section known as Facebook Marketplace has grown tremendously in popularity in recent years. With billions of users on Facebook, Marketplace allows you to reach a huge potential audience locally or anywhere in the U.S. You can list individual cards or entire collections for sale and interact directly with interested buyers. There are no listing or transaction fees. You’ll need to handle shipping, payments, and meetups yourself if selling locally. For casual sellers, Marketplace provides an easy way to move cards to eager collectors nearby.
Reddit – While not a traditional marketplace, the sports card trading subreddit r/baseballcards has over 115,000 members actively buying and selling cards. Sellers can create photo posts of individual cards or lots for sale and negotiate with interested buyers in the comments. No fees are involved and payments are handled directly between users, typically via PayPal Goods & Services for buyer protection. Shipping is the responsibility of the seller. Reddit isn’t ideal for high-volume sales but can be a good lower-pressure way to sell duplicates or find buyers for more niche cards. Just be sure to thoroughly check a buyer’s reputation.
Instagram – Instagram has become another popular platform for collectors and dealers to connect, with hashtags like #baseballcardsales helping surface listings. Sellers can create photo posts of cards for sale and allow buyers to message them directly to inquire or make offers. As with Reddit, there are no platform fees but you’ll need to handle payments and shipping yourself. Instagram isn’t as structured as dedicated marketplaces but provides good exposure within the baseball card community if you’re active on the platform already. Just be sure your profile looks trustworthy to potential buyers.
Local Card Shops – While less convenient than online selling, local independent card shops can be a good option, especially if you have a large collection to offload quickly at once. Shops will buy entire collections outright for a negotiated price, though you likely won’t get top dollar. They do the work of sorting, pricing, and reselling cards individually to make their profit. This is a hassle-free method if you want cash in-hand right away rather than piecemealing sales online. Call around to shops in your area to get quotes.
For selling individual cards or small lots, eBay remains a top choice due to massive traffic and ability to set your own prices. COMC and Sportlots are leaders for professional consignment of larger collections. Facebook Marketplace and local Reddit communities provide easy exposure locally. And shops are an option if you want a quick bulk sale. Consider factors like volume of cards, desired effort level, and needed timeframe when choosing the best platform to sell your baseball cards. With the right marketplace, you can earn some nice returns on those dusty cardboard treasures.
