For These Collectors, It’s Still All About the Cash

Even as the world increasingly moves toward digitised commerce, where transactions are conducted with the tap of a credit card and billions of dollars are moved electronically between banks, there is one group of people for whom hard cash is still king: collectors.

As an alternative asset class, collectible banknotes offer significant potential value to investors, and the market for these paper artefacts is thriving. Aris Maragoudakis , director of world currency auctions at Stack’s Bowers Galleries in Costa Mesa, Calif., estimates the hobby sees annual trade of well over $500 million globally.

In fiscal year 2016, the World Paper Money department at Stack’s recorded about $4 million in sales. By fiscal year 2024, this figure had risen to $14.5 million. The company reported an 18% increase in sales for world paper money (which doesn’t include U.S. paper-money numbers) in fiscal year 2023, followed by 25% growth in fiscal year 2024.

Elsewhere, the Noonans Mayfair London realised £5 million, or about $6.5 million, in world banknote sales in 2023, up from £2.5 million the previous year, a representative said.

The rise of digital technology has helped broaden the base of collectors. Online auctions, forums and databases have made it easier for collectors to connect, trade and research. Greater access to information about collectible money, as well as to collectible banknotes themselves, have transformed the hobby from a game of chance to a strategic pursuit where enthusiasts can actively search for and acquire valuable pieces.

“The advent of social media such as Instagram and WhatsApp have brought in a spate of new collectors, especially youngsters,” says Rezwan Razack , a specialist in vintage banknotes and chairman of the Indian chapter of the International Bank Notes Society, or IBNS.

While social media has made more people aware of older paper currencies and their histories, the declining use of physical banknotes has made them even more alluring and fascinating to collectors.

Where is the value?

Banknotes routinely become obsolete due to political shifts, security upgrades, monetary policies and technological advancements. The question is: Which ones are worthy possessions?

A plethora of factors underpin the desirability of collectible paper money. The major ones are:

• Condition: The condition of a piece can have a significant impact on its value. “There are bills that sell for $1,000 with a fold or two, but finding one free of any folds, stains, or tears could be worth several times that,” says Maragoudakis.

The condition of a bill is evaluated based on a 30-point scale ranging from poor to uncirculated crisp. Within each condition, a bill is given a number grade; a higher number—on a scale typically from 1 to 70—means the banknote is in better shape.

For example, a 10,000-yuan note issued in 1951 by the People’s Bank of China, graded Very Fine 20, sold for $150,000 at a Stack’s Bowers auction. Three years later at another Stack’s Bowers auction, a similar note in better condition, graded Almost Uncirculated 50, fetched $358,500.

• Serial number : Banknotes with striking serial numbers are often worth more to collectors than those without. On eBay, a rare polymer £20 bill with the serial number AA44 444444 received 16 bids and sold for more than £317.

A set of four exceptionally rare Chinese 1953 10 yuan notes from the People’s Bank of China recently sold for $432,000 because in addition to their quality, they were consecutive in serial number.

• Scarcity : The appeal and worth of banknotes, as with other collectibles, are often tied to their rarity.

For instance, high-value banknotes were often printed in limited quantities due to their significant purchasing power, says Hakim Hamdani , director at large and a collector at the Netherlands branch of the IBNS. When these high-denomination notes are discontinued, many people cash them in rather than keeping them as collectibles.

Take the 1921 10,000-shilling note from British East Africa (now Kenya and Tanzania), of which few were printed and issued. At that time, it was equivalent to about $2,000, a substantial sum in 1920s colonial Africa. When they were demonetized, most were redeemed, making the few remaining in private hands highly desirable.

Dennis Hengeveld , president of World Banknote Auctions in Sacramento, Calif., says that depending on the condition, some of these notes have fetched between $35,000 and just over $100,000 at auctions.

A rare $500 Canadian bill from 1911 brought C$528,750 (about $386,400) at a recent auction, the largest sum ever paid for a Canadian banknote. The specimen features the image of Queen Mary and is one of only four of the bills known to exist.

• Error notes : Governments often withdraw banknotes from circulation to deter counterfeiting, but also due to printing anomalies such as incorrect signatures, numerical discrepancies, misprints and typographical errors. Such deviations can elevate their value among enthusiasts.

In the U.S., double denominations—such as a front displaying a $10 bill and the reverse displaying a $20 bill—are the most prized error notes. The value of some of these pieces could top $85,000, according to Heritage Auctions.

How can I get started?

Despite the potential for a lucrative return, experts say the primary motivation for building a collection should be enjoyment and an appreciation of the history that banknotes provide. It would be best to build a collection with the idea of having fun, says Hengeveld of World Banknote Auctions, which was recently acquired by Stack’s Bowers.

Of course, it’s essential to do your due diligence to avoid fraud. Always buy notes from established dealers and confirm their authenticity with reputable grading services. Independent grading companies such as Paper Money Guaranty and Professional Coin Grading Service provide authentication and grading to ensure notes are genuine and their condition accurately assessed.

Auction houses and local dealers offer currency notes in different price ranges. Online retailers (eBay, Amazon.com, Collectibles & Currency), dealers and galleries (Certified Coin Exchange, George H. LaBarre), and numismatic shows (the MIF Paper Money Fair and World’s Fair of Money) are other useful sources.

As well, there is no shortage of stories where people discovered highly valuable collectible banknotes in attics, books, dressers and photo frames of deceased family members. In Ontario, a rare Canadian $500 bill from 1911 was discovered among the personal belongings of a deceased individual. The nearly discarded banknote, one of only three in existence, brought $322,000 at auction.

Those looking to dip their toes into collectible money may find valuable insights in trade magazines including Bank Note Reporter and the Greensheet, or books such as the U.S. Error Note Encyclopedia and Standard Guide to Small-Size U.S. Paper Money.

Additionally, Paper Money Guaranty, the Smithsonian Learning Lab and other websites can offer a wealth of information on various aspects of grading, collecting and how to properly care for banknotes.

Shipping cargo through an Arctic shortcut never made economic sense—until now.

Climate change and war in the Middle East are flipping the math that previously kept ships plying longer routes from Asia to Europe. A Chinese company on Saturday is starting the first regular cargo service to Europe through Arctic waters, seeking to reap the benefits of quicker travel time and less fuel use.

The shipper Sea Legend will dispatch the Dubai Tower from Ningbo, China, to Felixstowe in the U.K. on what it calls the Arctic Express, following a route along Russia’s north coast. The voyage by the vessel, which is capable of carrying 1,740 20-foot containers, is the biggest commercial step in the Arctic since a Maersk containership first completed the route in 2018.

Global warming is a big factor behind the new route, but it is not the only one. Nearly half the Arctic region’s summer ice—an area four times the size of Texas—has melted over five decades, clearing a fairly reliable path in the summer months. Meanwhile, high oil prices and attacks by Houthi rebels in the Red Sea have made the traditional routes costlier and more dangerous.

Beyond that, Beijing has ambitions to play a role in the Arctic’s future, lending a geopolitical dimension to the Chinese company’s shipping route.

Last year Sea Legend completed a trial run from Asia to Europe in a record 20 days. That is roughly half the time of a voyage via Africa’s Cape of Good Hope that many carriers now take because of the Red Sea uncertainty.

Fuel accounts for 70% or more of the costs while at sea, said Alan Murphy, a former Maersk analyst who runs research firm Sea-Intelligence.

Saving fuel by shortening the journey doesn’t automatically make a route profitable. Insurance premiums for the Arctic are 40% higher than the Cape of Good Hope route, said Jonathan Steenberg, an economist at credit insurer Coface. Sea Legend’s Arctic vessels are relatively small. And even after warming, an icebreaker is still sometimes needed to help the cargo ship.

But if the ship can go without an icebreaker, Coface said the Arctic route is now cheaper than a Cape of Good Hope voyage in some circumstances. It estimated that at current oil prices of around $90, the cost of shipping liquid bulk such as liquefied natural gas could drop roughly 33% compared with the Cape of Good Hope route, while dry bulk goods such as cereals would cost about 8% less.

The route is only passable in the summer and fall. Sea Legend plans eight voyages between August and late October, before conditions get too icy.

“It’s not the Suez Canal but it’s a significant number for the Arctic. It shows there is potential,” said Malte Humpert, founder of the U.S.-based Arctic Institute and author of a book on Chinese shipping in the Arctic.

Even in summer, ships have to navigate around dangerous ice floes and deal with rapidly changing weather. By the end of the shipping season in October, the sky is dark most of the time.

A Russian tanker suffered serious damage to its hull while sailing along the Arctic route despite being assisted by an icebreaker, its insurer, AlfaStrakhovanie, said Thursday, adding that it paid out roughly $650,000.

Coface estimates 3.5% of trade among East Asia, Europe and North America will be able to use Arctic routes within the next five years, representing $64 billion in goods.

Last summer, a record 23 cargo ships transited the Northern Sea Route, which hugs Russia’s north coast. That is tiny compared with the Suez Canal, where more than 30 ships transited daily.

Western companies that want to follow in Sea Legend’s path have to navigate treacherous politics. Russia claims sovereignty over the entire Northern Sea Route and permits for ship traffic are issued by its state-controlled nuclear operator, Rosatom.

“Western companies are in a tricky position,” said Humpert of the Arctic Institute. “At what point do they jump back in the water? When does it become economically necessary, and how do you weigh that against environmental risks and the political dimension?”

An alternative Arctic route, the Northwest Passage that connects the Atlantic and Pacific oceans via the Canadian Arctic, is less passable because it is dominated by narrow waterways where ice gets bunched up. The highest number of cargo ships completing the passage in a year was 13, in 2023.

China has declared itself a near-Arctic state despite not having access to Arctic waters. It depends on Russia’s goodwill to use the Northern Sea Route.

“Beijing is concerned that if they don’t establish a significant strategic presence in the Arctic now, it’s going to be more difficult in the future,” said Marc Lanteigne, expert in polar geopolitics at the Arctic University of Norway in Tromsø. However, he said, “China needs to be careful not to give the impression that they are trying to challenge the strategic order in the Arctic.”

Sea Legend didn’t respond to requests for comment.

Any polar venture contributes to China’s quest to master Arctic travel. The country also has three icebreakers and a support vessel currently on a monthslong scientific expedition north of Greenland. Scientific and commercial voyages can yield data about natural resources awaiting below melting ice caps and information for positioning nuclear-armed submarines.
