In 2019, the most expensive Yu-Gi-Oh card was the Shonen Jump 2013 Prize Card, Grandopolis, The Eternal Golden City. This is a card that cannot even be used in a Duel, due to the fact that it could win you the match if it attacks directly. In January 2019, a copy was for listed for sale at $18,999.99 USD on eBay.
Grandopolis is a Rank 8 XYZ monster that needs 3 Level 8 monsters to summon. It has 2800 ATK and 3500 DEF. He must be Special Summoned by Xyz Summon and no other way. If Grandopolis attacks your opponent directly and reduces his or her life to 0, if one of the original Xyz Materials was a Machine-type monster, you win the Match. While this is somewhat difficult to actually pull off, because it can win the match, like Victory Dragon and other similar Shonen Jump Championship prize cards, it can never be used in an official Duel.
There’s a replica of Grandopolis, The Eternal Golden City out there that was released in 2014. One replica copy was graded by Beckett Grading Services as a Gem Mint 9.5 and sold for an undisclosed best offer on eBay. There was another Grandopolis replica listed on eBay in January 2019 for $1200. If you absolutely want to own a Grandpolis, the Japanese version is available for $10 - $15 on eBay.
The runner up for the most expensive Yu-Gi-Oh card is another Shonen Jump Championship Prize Card. This is the 2017 Shonen Jump Championship prize card, a Link monster called Iron Knight of Revolution. Like Grandopolis, it also cannot be used in a Duel.
Iron Knight of Revolution requires 3 Machine-Type effect monsters to successfully Link Summon. When this Extra Linked card attacks your opponent directly and reduces their life points to 0, you win the Match. In many ways, this is probably the superior monster. In any case, a copy of Iron Knight of Revolution was listed on eBay for $11,999 in January 2019.
What’s the Most Expensive Playable Yu-Gi-Oh Card?
For a long time, the most expensive playable Yu-Gi-Oh card was Crush Card Virus. This is actually still the case in 2019.

Two other copies of the Shonen Jump Crush Card Virus were listed on eBay for $4,995 each.
Of course, if you really want to own a Crush Card Virus, a Gold Series 2008 copy sells for a little over $35.
