Online Marketplaces:
eBay – eBay is the largest online marketplace and has the most active collectors and buyers. You can sell individual cards or complete sets. It takes a small selling fee but gives you access to millions of potential customers. Taking good photos and providing accurate descriptions is important to get the best prices. Be sure to check recent sold listings to help price your cards competitively.
Collectors Universe Price Guides – PSA and Beckett both have their own marketplace sites where you can list cards for sale. Being PSA or Beckett graded cards tend to sell for higher prices. The market is not as large as eBay but collectors value the authentication a grading provides. Listing fees are higher than eBay as well.
Sportscard Forum – A popular discussion forum with a dedicated marketplace section. Catered specifically to sports card collectors so buyers may spend more than on eBay. Still a smaller pool of customers than eBay. No listing fees.
Local Card Shops:
Going to a local card shop gives you the advantage of an in-person evaluation and sale. Many knowledgeable collectors frequent shops to trade, sell, and buy. Shop owners know the market well and what cards local collectors want. They aim to make a profit when reselling anything they buy from you so expect to get slightly less than private sale value. Shops also often hold events that bring in more buyers. Downside is limited to local customers only.
Online Consignment Services:
PWCC – One of the largest online card auction companies. Do consignment sales of individual premium cards or full collections. They handle photography, description, promotion and sale. Take a commission (usually 15-20%) only if the card sells. Reach a global buyer base but their commission cuts into your profit.
Robert Edward Auctions – Another major auction house specializing in vintage/ valuable cards. Their auctions are well promoted and attract institutional/high-end buyers. As with PWCC they only take a commission on successful sales. Best option for moving high value/graded cards to the broadest market.
In Person Card Shows:
Attend local, regional or national sports card shows/conventions to set up a booth/table and sell directly. Costs typically $100-300 for a full weekend spot. Chance to meet collectors face to face and make spur of the moment/bigger bundle sales. Need to bring your own supplies. Large volume of potential buyers if its a major event. Downside is travel costs and risk of theft if wares aren’t secured.
The key is researching the best avenue based on the type/value of cards you have to sell. Factors like fees, accessibility to relevant buyers, and potential profit all influence the best option. With some trial and error you’ll gain experience on where your collection will sell fastest and for the highest prices.
