Belly, represented by the belly sign: (a Latin "esh" superimposed over a capital B), is the world's main monetary unit. It is almost exclusively depicted in paper form, although coins also exist. The belly has no fractional unit.
Distribution of Wealth
When Oda discussed the Doskoi Panda brand, he mentioned that the line was very expensive. With this in mind, to properly put the currency's value in a real world context, a 10,000 shirt is expensive to the people of the One Piece world.
Bell-mère was noted to be too poor to give her daughters everything they needed in life, and when Arlong invaded she had only a life's savings totaling at the time just 100,000 and had prior to this often been on a diet of just oranges to pay for the life she had to offer her daughters. She was the only one in her village unable to pay the full amount Arlong requested at the time of his arrival (100,000 per adult, 50,000 per child), and Arlong continued to demand this amount regularly from the residents of Cocoyasi Village resulting in years of struggle to pay the amount to avoid anyone being killed by Arlong. Arlong had agreed with Nami that she only had to bring 100,000,000 to buy her village back off him, an amount she took 8 years to amass and almost succeeded in reaching the goal simply by robbing pirates knowing they had access to more wealth than citizens. Notably also, Nami once demanded 1,000,000,000 from Igaram to protect his country's princess calling it a "measly" sum for a royal household to have, but later it was noted that the country did not even have this amount of wealth to offer as it was on the verge of civil war.
The Straw Hat Pirates considered themselves "wealthy" after gaining gold worth 300,000,000. When they lost 200,000,000 of it to the Franky Family they noted their remaining 100,000,000 was still enough to buy a decent second hand ship to continue their journey, even though their original amount would have bought them a brand new ship of much better quality (though Franky later used that very stolen 200,000,000 to build the crew a ship of great quality). The most affordable slaves are humans at 500,000 while 70,000,000 for a female unsplit mermaid is the highest starting bid for any race. As such, all kidnapping groups seek them out and they present the most profitable slaves at auctions, and the storyline hints they can run well into the 100,000,000s, being noted only to be bought by only the wealthiest of the One Piece world inhabitants. Rare Adam Wood, being sold on the black market can reach the price of about 200,000,000.
However, to a World Noble, a bid of 500,000,000 seems to be an insignificant amount of money to them judging by the way Saint Charlos bid in the Human Auctioning House. And most note worthy, he bid this amount off the mark and no one else could counter his bid in the auction house ending the sale of Camie then and there. His father merely noting his 'waste of money', indicating they have even more wealth than this and while this amount is still considered a waste, it means they do not go through the same scale of financial concerns as the rest of the world. Also, while the limit of bounties is unknown, the highest known bounty belongs to Marshall D. Teach, whose bounty is 2,247,600,000. However, the fact the officials would consider offering this amount also indicates that the treasury for holding bounty rewards has a considerable amount of money to offer or are at least willing to offer and part with that high of an amount. The Ope Ope no Mi, considered the "Ultimate Devil Fruit" due to its medical potential and ability to grant eternal life, is so valuable that the Marines were willing to pay as much as 5,000,000,000 for it, showing that the World Government is willing to and capable of affording such prices. Donquixote Doflamingo offered to sell Riku Doldo III the rights to rule Dressrosa for 10,000,000,000, in lieu for taking the country by force; Riku stated such a ransom is impossible to acquire by Dressrosa kingdom alone.
So it would seem that the difference between the amount of money possessed by the richest and poorest of the citizens, the poorest families can have less than 100,000 life savings while the richest have a staggering 500,000,000 or more as pocket money.

Although the belly is a universal currency used nearly worldwide, some isolated countries have their own currencies. As of now, two such currencies were mentioned:
- Extol (エクストル Ekusutoru?) is the currency used in Skypiea. Normally, it is written similar to the Belly with an "esh": only with an "E" instead of a "B": . The extol seems to be pegged to the belly, as there are 10,000 per 1. Nothing else is known about the extol.
- Gor (ゴル Goru?) is used on Amazon Lily. Nothing else is known about it.
- Gold (
金Kin?) is used in Wano Country. 500 Gold is considered to be a hefty price. Nothing else is known about it.
- In the Boss Luffy specials, the currency ryo-belly is used. This currency has no banknotes, only coins, and mirrors the Tokugawa coinage that was used in real-life Edo Japan.
- In the one-shot story by Eiichiro Oda, Wanted!, a currency with an unknown name is used. This currency abbreviated looks like belly, extol, or dollar, only with a Z in place of the other letters. Whether this currency is available in coins, banknotes, or some other form is unknown.
Translation and Dub Issues
It should be noted that because of the phonology, multiple English spellings exist; the most common among fans is "beli", although "beri" is also used. "Berri" and "belly" are used too but are somewhat uncommon. "Berry" for singular and "Berries" for plural are used in the English versions. Oda has spelled it as "belly" on the actual bills.
- In the SBS of Volume 53, Oda showed the designs on the coins and notes of One Piece.
- Nami's eyes tend to take the shape of the symbol of belly when she hears that a large amount of money is involved. Especially when explaining that what she is doing has nothing to do with the money.
- In appearance and denomination, the belly closely resembles the Japanese Yen (日本円 Nihon En?). The characters Yukichi Gaikotsu, Ichiro Kumaguchi, and Hideo Usaguchi portrayed on the belly banknotes are a pun on Hideyo Noguchi, Ichiyō Higuchi and Fukuzawa Yukichi portrayed on the corresponding yen banknotes. "Gaikotsu", "Kuma", "usa" mean skeleton, bear and rabbit respectively.
- The belly' symbol closely resemble Thailand's baht: ฿ (baht) / (belly).
- In the One Piece game, One Piece: Pirate Warriors 2, it is said that the largest bill comes worth 10,000 belly.
