There are many sites online that allow users to sell their Yu-Gi-Oh cards: two of the most popular sites are eBay and TrollAndToad.com. Both sites allow users to sell rare cards as singles and common cards in bulk.
As of 2014, while TrollAndToad.com requires a seller minimum of $10 worth of cards based on the site's price guide, eBay allows sellers to offer as many or as few cards as they want. EBay's Yu-Gi-Oh selling guide recommends offering cards in large lots in order to increase the chance of sale. For selling individual rare cards, such as holographs, eBay recommends offering buyers incentives, such as bonus cards if an auction reaches a certain price.
