What is the rarest banknote in the world?

No single note holds an undisputed title, because rarity is counted issue by issue and several notes are down to one surviving example. The strongest published claim belongs to a Curacao 250 Gulden of 1918 carrying serial number 001, which Heritage Auctions described as "arguably the rarest banknote in existence since it is the only extant example" (Heritage Auctions, April 2022).

Heritage's reasoning is worth following, because it is how professional rarity claims are made. The Curacaosche Bank issued roughly 400 of that 250 Gulden type. High denomination colonial notes were redeemed rather than kept, and the bank's records show the rest going back. The note that survived happens to be the first one printed. That is a census claim, a printing record and a physical object lining up, and it is a much stronger statement than any adjective.

Other notes sit at the same level with equally specific documentation. The Dominion of Canada $2 of 1870 payable at Victoria, sold in January 2025, is the only known example from a shipment of 24,000 notes to the Pacific coast that had been presumed entirely lost. Even the National Currency Collection in Ottawa does not hold one (Stack's Bowers Galleries, January 2025).

The rarity table: notes ranked by documented survivors

The table below lists banknotes whose surviving population has been stated publicly by a named source, ordered from the notes known in single examples down to those known in the dozens. The last column gives the most recent public sale this page could document, which is frequently decades apart from the one before it.

Counts are reproduced as the named source states them and are not combined or adjusted. Sources, all as published by CoinWeek: Curacao and Angola, Canada 1870 $2, Grand Watermelon census, 1928 $10,000 note, 1928 $5,000 census, Fr. 377 Watermelon, Kang Yongjie census, Suriname and Germany, Netherlands Bank, $100,000 Gold Certificate.

How is a banknote's rarity actually established?

Four kinds of evidence produce a survivor count, and they are not interchangeable. Printer and treasury records say how many were made. Redemption records say how many came back. Grading service population reports say how many have been certified. Specialist census projects such as Track and Price track individual notes by pedigree across sales.

Start with the production figure, because it sets the ceiling. PCGS records that only 16,000 notes of the Fr. 379a Grand Watermelon variety were printed, and that just two are known and available to collectors (PCGS Banknote, July 2020). The gap between 16,000 and two is the whole story of high denomination American paper.

Redemption records close that gap. The Curacao examples above are the clearest case: Heritage could say how many of each type were printed, how many the bank took back, and therefore what was left. When an issuing bank keeps that ledger, a rarity claim stops being an estimate.

Population reports are the modern workhorse but they need careful reading. A line such as "the first and only example graded in the PMG Population Report" counts certified notes, not surviving notes. Uncertified examples can and do exist. It is still strong evidence, especially for issues that specialist collectors have been submitting for twenty years, and it is the count most world banknote descriptions rely on. Our guide to PMG versus PCGS explains how each service reports its data.

Census projects are the strictest form. Track and Price follows individual notes rather than certification events, which is why Heritage was able to say in 2024 that about 35 examples of the Fr. 377 Watermelon note survive from 120,000 printed, eight of them in institutions (CoinWeek, August 2026). That works out to roughly one survivor for every 3,400 notes made.

What is the difference between a rare banknote and a valuable one?

Rarity counts survivors. Value counts buyers. A note with three survivors and thirty collectors chasing it will outprice a note with one survivor that almost nobody collects, which is why the rarest banknote in the world and the most expensive banknote in the world are not the same object.

The 1975 China 2 Yuan proof that Stack's Bowers sold in Hong Kong in March 2019 makes the point. It was a proposed design that never reached circulation, and it brought $240,000 against a pre-sale estimate of $75,000 to $100,000 (PMG, March 2019). Chinese paper money has one of the deepest collector bases in the world, and price follows that depth.

Run the comparison the other way and the effect is just as visible. Several Surinamese and Angolan notes in the table above are known in single figures and sell in the tens of thousands, because the number of people assembling those series is small. Depth of demand, not scarcity alone, is what turns a count into a price. The same logic drives our guide to what determines banknote value and the ranked results on most valuable world banknotes.

Which United States banknotes are the rarest?

The rarest American notes cluster in two places: nineteenth century issues that were redeemed almost completely, and twentieth century high denominations that the Treasury destroyed on return. The 1837 $100 Interest Bearing Note is unique as an issued example, and the Fr. 202a $50 of 1861 is the only collectible issued note from the entire 1861 Interest Bearing series.

Interest Bearing Notes explain why so many American rarities are unique rather than merely scarce. They paid six percent per year for two years, banks rather than the public held them, and at the end of the term nearly all were redeemed. The Fr. 202a that Stack's Bowers sold in August 2018 has an unusually complete paper trail: a Rarcoa sale in August 1970 at $10,000, a Currency Auctions of America sale in May 2001 at $605,000, a Heritage sale in February 2005 at $368,000, and then $1,020,000 in the Joel R. Anderson Collection (Stack's Bowers, August 2018).

The Anderson sales of 2018 and 2019 are the reason so much of the American census is now public. Four auctions totalling $34,126,980 made it the most valuable United States paper money cabinet ever sold at auction, and each catalog stated the population for the note in front of it: the only privately held Fr. 187b $1,000 Legal Tender of 1880, the only publicly available Fr. 209a $500 Interest Bearing Note of 1861, the 1869 $500 and $1,000 Rainbow Notes as the only examples in private hands (Stack's Bowers, March 2019). Our page on the most valuable United States banknotes ranks those results by price instead.

One American rarity sits outside every ranking. The Series 1934 $100,000 Gold Certificate was produced in a run of 42,000 between December 18, 1934 and January 9, 1935, purely for transfers between Federal Reserve Banks. Issued survivors are held by the Smithsonian, the Bureau of Engraving and Printing and the Federal Reserve Banks of Richmond and San Francisco. The only piece a collector can hold is a uniface front specimen with a blank back reading "SPECIMEN NOT NEGOTIABLE", which changed hands privately in August 2025 (CoinWeek, May 2026).

Which world banknotes are the rarest?

Outside the United States the rarest notes are colonial and early central bank high denominations, where small print runs met near total redemption. Curacao, Suriname, the early Netherlands Bank and Zanzibar produce more single figure populations than any other group, and the counts usually come from the PMG Population Report.

Zanzibar is the field's shorthand for difficulty. The protectorate began printing its own money through Waterlow and Sons in 1908 in denominations of 5, 10, 20, 50 and 100 Rupees, and added a 500 Rupees note in 1920. Stack's Bowers, which brokered a private treaty sale of a complete Waterlow set with Spink in 2017, called the 500 Rupees one of the most difficult banknotes in the world to obtain (Stack's Bowers, August 2017). No published source gives a survivor count for the 500 Rupees, so this page does not give one. The smallest denomination reaches auction more often: a Zanzibar Government 1 Rupee of 1.9.1920, Pick 1, graded PMG Extremely Fine 40, brought $45,600 at Heritage in March 2023, the highest graded Zanzibar note offered at auction to that point.

Early Dutch and Dutch colonial paper is the other deep seam. The Netherlands Bank 100 Gulden of 1814 to 1838, Pick A6, which Heritage sold for $114,000 in June 2025 from the collection of Alphons Toele, is the first and only example in the PMG Population Report and possibly the only one extant in its format. That sale set a record for any Dutch note (Heritage Auctions, June 2025).

Hong Kong contributes a different kind of rarity, the earliest surviving example rather than the smallest population. An Oriental Bank Corporation $5 handwritten with the date June 1, 1860 and graded PMG 12 Fine sold at Dix Noonan Webb on August 26, 2021 for 161,200 pounds against an estimate of 30,000 to 50,000 pounds. PMG confirmed the handwritten date, which established it as the earliest known fully issued Hong Kong banknote to survive (PMG, August 2021).

Why do so few high denomination notes survive?

High denomination notes were working instruments for banks, not money that people kept. They were issued, used for settlement, returned to the issuer and destroyed, which is a survival mechanism running in reverse. The American record shows the process in numbers: at the end of 1945 there were 1,405 $5,000 notes outstanding, and by the end of 1968 only 634 remained.

On July 14, 1969 the Federal Reserve and the Treasury announced that the $500, $1,000, $5,000 and $10,000 denominations would no longer be issued. Reserve Banks sent their remaining stock to the Treasury for destruction and began destroying large denomination notes that came back through normal banking channels, a policy that has continued since (CoinWeek, September 2026).

The Series 1928 $5,000 note shows what that leaves behind. Census research records 18,244 printed across the participating districts, with only 20 confirmed survivors and 27 total examples reported. Kansas City received 720 of them and two are documented today, a population recognised by both Heritage Auctions and Track and Price. One of those two, catalogued Fr. 2220-J and graded PMG Extremely Fine 40, realized $228,000 at Heritage on September 13, 2024.

Which real rarities can a collector actually pursue?

Notes known in single figures are effectively closed to new collectors, but genuine scarcity exists at every price level. The productive route is to pick a series where the population data is published, then work down the census rather than up the denomination ladder.

Three approaches work in practice. Specimen and proof material often survives in counts the issued notes cannot match, and it is catalogued clearly, which is why our guide to specimen notes is a useful starting point. Replacement printings are the second route, and star notes and replacement notes reward a checklist rather than a budget. The third is condition rarity, where a common note is scarce in high grade, and that is where a certified population report earns its keep.

Certification is what makes a rarity claim portable. A note described as one of four known is only worth that description if a third party has seen it, which is the argument in our comparison of graded versus raw banknotes and the ladder in our banknote grading guide. If a catalog reference such as Pick A6 or Fr. 379a is unfamiliar, our catalog number guide explains the systems and the banknote glossary defines the rest. For the price side of the same material, see the auction record table and the story of the Grand Watermelon note.
