According to multiple sources, the most expensive Yu-Gi-Oh! card is the Tournament Black Luster Soldier, which has sold for as much as $2 million. However, it is worth noting that this card is extremely rare, with only three ever made and given out as prizes for first, second, and third-place finishers at the 2017 World Yu-Gi-Oh! championship. Other expensive cards include Tyler, The Great Warrior, which sold for $311,211, and Blue-Eyes White Dragon LOB 1st Edition, which has sold for as much as $85,000. The value of these cards is determined by factors such as rarity, limited printing, age, and condition.
