The essentials in 30 seconds: from the elusive “One Piece” treasure to the rarest Devil Fruits, along with the indecipherable Poneglyphs and Ancient Weapons capable of wiping an island off the map, Eiichiro Oda's universe is brimming with objects that pirates, marines, and collectors fight to get their hands on. This feature takes a tour of the manga's most coveted treasures—and their real-life counterparts to bring home.
In the world of One Piece, everything revolves around desire. A legendary treasure sends thousands of pirates out to sea, a Devil Fruit can tip the balance of power, and a simple engraved stone can rewrite the history of the world. These objects are not mere narrative accessories: they are the driving force behind the entire plot, the reason Luffy and his crew have been crossing the Grand Line for more than twenty-five years of publication.
We've listed the objects that obsess characters—and fans—the most. The ultimate treasure, some of the most powerful fruits ever eaten, remnants of a forgotten century, weapons capable of destroying the world: here is the ranking of the most sought-after artifacts in One Piece, along with a few real-life collectibles for collectors.
1. The “One Piece” Treasure: Everyone's Obsession on the Grand Line
It's impossible to start this list without mentioning the object that gives the series its name. Hidden somewhere on the island of Laugh Tale, the treasure amassed by Gol D. Roger during his journey around the world remains, more than twenty years after his execution, the ultimate Holy Grail for all pirates sailing the seas. Its mere existence was enough to trigger the Great Pirate Era and drive thousands of adventurers to risk their lives on the Grand Line.
What makes this object so fascinating is that no character—not even Roger himself in his final words—has ever revealed its exact nature. Glory, forbidden knowledge? Fan theories have been piling up for decades, and our dedicated article on Laugh Tale and the treasure's final island details the clues Oda has left throughout the arcs.

There are said to be just under 200 Devil Fruits in the world of One Piece, but not all are created equal. Some are fiercely hunted by the great powers, to the point of sparking wars or multibillion-berry auctions. Here are the most coveted ones in the story.
The Ope Ope no Mi: the 5-billion surgical fruit
Trafalgar Law's surgical fruit is probably the most “expensively” hunted in the entire series: its ability to grant eternal youth makes it the top obsession of the World Government and the Marines. Our complete analysis of Law's fruit and its record value explains why Doflamingo, the Fleet Admiral, and the Gorosei all fought over it.
The Gomu Gomu no Mi / Hito Hito no Mi Model Nika
Long believed to be a simple Paramecia fruit, Luffy's power turned out to be the mythical Sun God Fruit, capable of bending reality like rubber. A power so dangerous to the established order that the World Government erased every trace of it from the history books for eight hundred years. Find all the details in our feature on Gear 5 and the transformation into the Sun God.
The Mera Mera no Mi and the Yami Yami no Mi
The rivalry between Sabo and Blackbeard over Ace's fire fruit perfectly illustrates how these powers change hands in bloodshed. As for Blackbeard's darkness fruit, capable of canceling out any other power, it remains one of the most terrifying artifacts ever bitten into. To understand the mysterious origins of these powers, head to our article on the origin of the Demon Fruits.
| Demon Fruit | Holder | Why it is coveted |
|---|---|---|
| Ope Ope no Mi | Trafalgar Law | Operation for eternal youth, estimated value of 5 billion |
| Hito Hito no Mi Model Nika | Monkey D. Luffy | Mythical fruit erased from history, with nearly unlimited power |
| Mera Mera no Mi | Sabo | Ace's legacy, absolute control over fire |
| Yami Yami no Mi | Blackbeard | Can cancel out any other Demon Fruit |
| Gura Gura no Mi | Blackbeard | The most destructive weapon ever given to a man |

3. The Poneglyphs: the World’s Forbidden Memory
Impossible to destroy and engraved eight hundred years ago by a forgotten people, the Poneglyphs are undoubtedly among the objects most sought after by the World Government itself. They are divided into two categories: historical Poneglyphs, which recount the Void Century, and the four Road Poneglyphs, which together indicate the route to Laugh Tale.
Only a few characters, such as Nico Robin, know how to decipher them—a skill so dangerous that it led to the destruction of an entire kingdom. Learn everything about how they work and what they contain in our guide “The Poneglyphs: How to Read the World’s History”, and about the one still missing from the crew in the mystery of the final Road Poneglyph.
What makes these stones so precious is that they contain truths the World Government has tried to erase for centuries—a subject explored in depth in our article on the Void Century.
4. The Ancient Weapons: Pluton, Poseidon, and Uranus
While the Poneglyphs are objects of knowledge, the three Ancient Weapons are objects of pure destruction. Created eight hundred years ago, they are said to possess the power to wipe the world off the map on their own, which explains why the World Government hunts them as relentlessly as Roger’s treasure itself.
- Pluton: a battleship capable of sinking an entire island on its own, whose blueprints were entrusted to Franky’s family.
- Poseidon: revealed to be Shirahoshi, the princess capable of communicating with the Sea Kings.
- Uranus: the last Ancient Weapon, whose nature remains completely mysterious to this day.
For a detailed analysis of these three artifacts and their implications for the rest of the story, our article “The Ancient Weapons: Pluton, Poseidon, and Uranus Explained” remains the definitive resource on the subject. To explore the power struggles surrounding these objects further, the page One Piece: Everything About the Legendary Treasure summarizes the main theories circulating among fans.
5. Legendary Swords: Yoru, the Wazamono and the Saijo O Wazamono
The coveted objects in One Piece are not all mystical: some are simple weapons forged by human hands, yet made legendary by the strength of their wielders. This is the case with the 12 Supreme Grade Swords, the Saijo O Wazamono, of which Yoru—Dracule Mihawk's black sword—is considered the most powerful of all time.
Zoro himself already owns two: Enma and Wado Ichimonji, a sword that once belonged to Kozuki Oden. Find the complete ranking of these legendary blades in our article “The 12 Supreme Grade Swords”.

6. Wanted Posters: When a Head Becomes a Coveted Prize
Last on this list, but certainly not least: the bounty itself. A wanted poster has no material value, yet every pirate dreams of seeing their face plastered across the World Government's Wanted posters—the ultimate proof of their danger. The higher the bounty climbs, the more bounty hunters flock in—a vicious cycle that has turned Luffy and his crew into the Marines' top-priority targets.
For an original gift inspired by this tradition, the Wanted posters collection lets you decorate your room with the bounties of the Straw Hat crew members.
For fans who want to bring several of these iconic figures together on the same shelf, the Supernova Trio diorama figure brings together three of the most wanted pirates on the Grand Line in the same battle scene.
Those who want to own a fragment of this coveted world without sailing the Grand Line can also turn to the Gol D. Roger alternative-art cards or the Ope Ope no Mi Devil Fruit figurine, two highly sought-after pieces among the store’s collectors.
Frequently asked questions
Has the “One Piece” treasure already been revealed in the manga?
No, to date Eiichiro Oda has never revealed the exact nature of the treasure hidden at Laugh Tale. Only Roger and his crew, along with Whitebeard, know what it contains.
How many Road Poneglyphs are there?
There are four in total. Together, they indicate the exact path to Laugh Tale, the last island of the Grand Line.
Which Ancient Weapon is the most mysterious?
Uranus remains completely unknown to readers to this day, unlike Pluton (a battleship) and Poseidon (Shirahoshi), which have already been identified in the story.
Why is Law’s fruit valued at 5 billion berrys?
Because the Ope Ope no Mi is the only power capable of granting its user eternal life—an operation that Law specifically refused to perform on Caesar Clown or the Fleet Admiral.
Can faithful replicas of these legendary objects be found?
Yes: Devil Fruit figurines, miniature swords, trading cards, or Wanted posters let you recreate part of the Grand Line world at home, without ever having to face the Marines.
