Secret Wonders Master Set Checklist & Cost

Variants in the Secret Wonders master set

Most of the Secret Wonders master set comes from three plain families: Reverse Holo with 130 slots, Normal with 110 and Holo with 22. Reverse holo copies exist for the Common, Uncommon, Rare and Rare Holo cards, which is why that family is so large. The remaining slots are special printings: four separate Normal families named for players, Jason Klaczynski, Michael Pramawat, Tristan Robinson and Yuka Furusawa, at four slots each, plus a Holo Foil Cracked Ice family of three. Each of those is its own slot in the binder.

Where the Secret Wonders master set's cost sits

The Secret Wonders master set cost is concentrated at the top: the ten most valuable slots hold 45 percent of the total, while the lower-value half of the priced slots adds up to just 4 percent. By finish, reverse holos carry 48 percent of the value, holos 43 percent and normal prints only 8 percent, so the 152 normal slots matter little to the total. Condition changes the picture sharply: an LP and up master set sits 50 percent below the Near Mint total, and an MP and up set sits 69 percent below it. 300 of the 312 slots carry a price, as of October 24, 2026.

Hardest Secret Wonders master set slots

Five slots hold 33 percent of the Secret Wonders master set's total value. The Gardevoir Holo, a Rare Holo LV.X, ranks first, followed by the Lugia Holo, a Rare Holo, and then the Charizard Reverse Holo, also a Rare Holo. The Mew Holo ranks fourth and the Lugia Reverse Holo fifth. Two of the five are variants rather than the card's main print: the Charizard and Lugia reverse holos. That is the part of this master set that tends to surprise people, since a card's reverse holo can sit among the highest-value slots on its own.

How the Secret Wonders master set compares

At 312 slots, the Secret Wonders master set is about 1.2 times the Diamond & Pearl era median of 270, so it is somewhat larger than a typical set of its era. By master set value it ranks 8th of the 11 comparable sets in the era. The previous set, Mysterious Treasures, has 270 slots and a master set that holds less value. The next set, Great Encounters, is smaller at 247 slots and its master set also holds less value, which makes Secret Wonders the larger and higher-value job of the three.
