A one-of-one Cristiano Ronaldo trading card has fetched $1.35 million in a private sale, setting a new benchmark for the most expensive Ronaldo card ever. This transaction, which occurred yesterday, underscores the escalating value of football memorabilia.

The ultra-rare green 2018 Panini Kaboom card, depicting Ronaldo during his tenure at Juventus, achieved a perfect PSA 10 rating, signifying its flawless condition. This sale also positions it as the second most expensive football trading card ever recorded.

The surge in value is linked to Ronaldo's enduring global recognition and his continued presence in the sport. His recent inclusion in Portugal's World Cup squad, marking his sixth appearance in the tournament, alongside his continued high-level play at 39, fuels his commercial appeal across various sectors.

The market for sports trading cards, particularly football collectibles, has seen "explosive growth" in recent years. Factors such as rarity, condition, player fame, and brand all contribute to a card's valuation. Ronaldo and Lionel Messi's memorabilia consistently dominate this market, a phenomenon attributed to their iconic rivalry and storied careers.

Previously, the highest price paid for a Ronaldo card was $420,000 for a 2015 Panini Flawless Finishes Black card, which also featured a one-of-one designation and a perfect autograph grade, though its overall condition rating was a 7. The 2018 Panini Kaboom cards were not part of a public release but were distributed through a Panini Rewards program.
This latest sale follows closely on the heels of Ronaldo's first Saudi Pro League title with Al Nassr. While this specific sale has set a new high, it's worth noting that a 2004-05 Panini Mega Cracks Lionel Messi Rookie Card (PSA 10) previously sold for $1.5 million in a private sale, making it the current most expensive soccer card in history.
