Like with any Trading Card Game series, Yu-Gi-Oh! has rare cards worth from hundreds to hundreds of thousands of dollars each. The rarest Yu-Gi-Oh! cards were special tournament prizes, with few being released. Although useless in an actual duel, these cards are valuable and highly sought after even though very few ever are put up for sale.
The list of rarest Yu-Gi-Oh! Cards vary from site to site, but basically, the following are named as some of the rarest (in no particular order):
- Bandai Version Swords of Revealing Light - released in April 1998 but never outside of Japan with the price estimated from a couple hundred to a few thousand dollars
- First Edition Blue-Eyes White Dragon - part of the first official set of Yu-Gi-Oh! Cards released in Japan
- Dark End Dragon - only the top players received this prize card in the 2009 Yu-Gi-Oh! Tournament
- Skuna, the Leonine Rakan – only a few were given out as prizes at the Yu-Gi-Oh! World Championship in 2009
- Gold Sarcophagus - only 25 copies of this card were ever made, and they were presented to the top-class duelists in the 2005 and 2006 trading card championships
- Shonen Jump Championship Cyber Stein - approximately 126 cards in total were released between 2004 and 2006
- Armament of the Lethal Lords - another prize card, this Yu-Gi-Oh! was awarded to players in the World Championship of 2006
- Blue Eyes Ultimate Dragon – a one-of-a-kind tournament prize given to the winner of the 2001 Asian Championships
- Tyler the Great Warrior - a one-of-a-kind card specially made for Tyler Gressle’s Make-A-Wish Foundation wish. Tyler was diagnosed with a rare form of liver cancer in 2002. At the time, Tyler’s medical prognosis didn't look too good. So, Make-A-Wish Foundation worked to make his dream come true
- Tournament Black Luster Soldier - interestingly named as the number one rarest card on all platforms! This one-of-a-kind card was the prize of the first-ever Yu-Gi-Oh! Tournament in 1999. The winners of this inaugural tournament remained masked with their begrudged prize for many years until the Black Luster Soldier card listed for sale in 2013. The seller demanded an eye-popping $10 million, but it was reported to be sold for $2 million. Considering its high value and its unique nature, the Tournament Black Luster Soldier is the winner of the rarest Yu-Gi-Oh card ever in the world.
