Pokemon TCG: The 8 Most Valuable X & Y Era Booster Boxes (2024)

The X&Y era features incredibly expensive Pokemon TCG sets, from Primal Clash and Ancient Origins to XY Evolutions. Given their release dates, these sets are creeping closer to vintage categorization as time goes on, and there's no telling where the Pokemon market may be in a few years.

After looking at some of the most expensive booster boxes from the Sun & Moon era, there's no doubt that X&Y will feature several expensive sets, including a few that sell for well north of $500. These are the most expensive Pokemon TCG booster boxes in X&Y.

8 Steam Siege – $373

Storming Up The Charts

Steam Siege didn't quite take off in the same way that some of the other most valuable X&Y era booster boxes did, as this set lagged behind others for much of its existence. Though there are some nice cards like the Gardevoir EX and other versions, Gardevoir is the only real draw of the set.

If you like Volcanion or some of the other XY Pokemon, then you'll also find those in Steam Siege, but nothing unique sticks out about this set in either Pokemon included or design.

7 Fates Collide – $492

Trainers & Eeveelutions Everywhere

Fates Collide features a fairly even blend of amazing Eeveelution art and some of the most valuable full-art Trainer cards in the Pokemon TCG. With N leading the set in value, Alakazam, Umbreon, and Shauna round out the top four chase cards – all of which eclipse the $40 mark.

Aside from the top cards, Fates Collide has a solid supporting cast, but not enough to catapult it into the top-tier of X&Y sets, as some of the best X&Y booster boxes are packed with popular Pokemon.

6 Primal Clash – $568

A Legendary Group

Primal Clash is a great example of a well-rounded set that boasts a strong cast of Pokemon to collect, including multiple versions of legendary Pokemon. Groudon and Kyogre are the most desirable Pokemon to find in Primal Clash, with the set's name alluding directly to their age-old battle.

Primal Clash perfectly encapsulates the action and desperation each legendary Pokemon feels in their intense battle, but Groudon earns the title as the most valuable card in Primal Clash. With almost a $20 difference between Groudon and Kyogre, it seems this Primal Clash has a clear winner.

5 Roaring Skies – $617

And A Soaring Price

The spiritual predecessor to Sword & Shield's iconic Evolving Skies, this booster box sets an excellent example for its successor. While some of the most valuable Evolving Skies cards eclipse those found in Roaring Skies by a wide margin, both sets boast stunning Rayquaza artwork.

The X & Y designs are notoriously busy and intricate, but the fierce spirit of Mega Rayquaza shines through this card. While the artwork in both sets couldn't be more different, Roaring Skies set the tone for any set carrying "skies" in its name, coming in with a value above $600.

4 BREAKthrough – $640

A Myriad With Mewtwo

Some of the most beautiful full art cards in the Pokemon TCG feature multiple Pokemon sharing the spotlight in some seriously gorgeous scenes. This Mewtwo is the perfect example of BREAKthrough's unusual designs that sparked a shift in future TCG generations.

While BREAK cards never quite gained the same traction, combining Magnezone, Chesnaught, Cresselia, and Mewtwo is something that could only happen in full-art designs. This set features some powerful Pokemon in intimidating poses, but there's an even more valuable BREAK set out there.

3 BREAKpoint – $755

Making Waves Near The Top

Regardless of which chase cards you prefer, the BREAK sets took a leap of faith with some of the most standout Pokemon TCG artwork of all time. Shiny Gyarados makes a rare appearance in this set and boasts four separate artworks to collect.

Aside from the Gyarados love, two Trainer cards – Skyla and the Delinquent – round out the top three cards in BREAKpoint. While the two most valuable X&Y sets are more typical of what you can expect in this era, the BREAK sets deserve credit for switching things up.

2 XY Evolutions – $832

Starring Mega Starters

Evolutions is one of the most beloved Pokemon sets ever, as some of the best Pokemon from the original 151 appear as Mega Evolutions for the first time in the Pokemon TCG.

The Mega Charizard Y artwork leads the set, but a reprint of the Charizard art from the original base set sits in the second spot. XY Evolutions boasts one of the most expensive booster boxes from the X&Y era due to its fantastic homage to nostalgic Pokemon.

1 Ancient Origins – $940

A Case Of Deja Vu

No, you're not seeing double – the most valuable X&Y booster boxes feature two products with similar Mega Rayquaza artwork in Roaring Skies & Ancient Origins.

Though Rayqaza is the undisputed chase card, Groudon and Kyogre both appear in X&Y's most valuable booster box set. At just shy of $950, Ancient Origins takes the tentative crown for the most expensive X&Y sets, but Phantom Forces may have something to say about that once there's more sold data to observe.
