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 demonetised, 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.

Countries in Asia-Pacific will need to spend big to adapt to climate change. But the cost of inaction could be higher, according to a new report by the Asian Development Bank.

Left unchecked, climate change could punch a 17%-sized hole in the region’s economic growth over the next decades, the Manila-based bank said Thursday.

“The window to stay within the 1.5°C target of the Paris Agreement is rapidly closing,” the ADB said.

The international treaty aims to limit the average rise in global temperatures to that threshold, beyond which experts expect climate change to have increasingly disastrous consequences. In the nine years since the agreement was adopted, inaction has put that goal nearly out of reach, the multilateral bank said.

With greenhouse-gas emissions reaching record highs, nations need to dramatically increase—and immediately start delivering—efforts to get on track for 1.5°C, a United Nations Environment Programme report said last week. Failure to do so will lead to debilitating impacts to economies, the report said.

Asia-Pacific’s position in the climate crisis is a tricky one: it’s both home to some of the most vulnerable economies and a major polluter, contributing over 50% of global GHG emissions.

If emissions breach critical levels, ADB estimates climate change could reduce Asia-Pacific’s gross domestic product by 17% in 2070. Rising sea levels threaten coastal assets and populations, while heat waves would sap labor supply and productivity, and climate-dependent sectors like agriculture, forestry, and fisheries face shocks that will stifle output.

Estimates from the Deloitte Economics Institute calculate that about 75% of Asia-Pacific’s GDP is at high risk of climate disruption. This stands to affect at least half of the world’s labor force, which is in the region and in vulnerable industries. Climate inaction could lead to regional economic losses of about $96 trillion by 2070, the institute said in a report.

Asian countries have made strides toward decarbonising, but just maintaining policies implemented so far will lead to dangerous levels of global warming, the ADB said.

Taking the right type of action won’t come cheap. Estimates for Asia vary widely, in part due to different geographical definitions, but consensus is that funding is well below where it needs to be.

The ADB report estimates Asia-Pacific needs to invest anywhere from $102 billion to $431 billion annually to adapt to climate change. That far exceeds the $34 billion committed over 2021-2022.

Globally, the U.N. calculates the net-zero transition needs $0.9 trillion to $2.1 trillion a year between 2021 and 2050. That “is substantial but manageable in the broader context of the close-to-US$110 trillion global economy and financial markets.”

It remains technically possible to get on a 1.5°C pathway, as solutions like solar and wind power hold promise for fast, sweeping emissions cuts, the U.N. report said.

Getting back on track could be a big boost for Asia-Pacific economies.

The region is well-placed to benefit from the energy transition, the ADB said. It has massive potential for renewable-energy generation and can produce some of the world’s cheapest renewable electricity, it said. Advantages like fast-growing economies, a large workforce and strong manufacturing base equip Asia to develop the technologies needed for global decarbonisation.

That presents a wealth of opportunities for investors.

If governments formulate consistent policies and build climate-oriented financial systems, that can draw the private capital that’s key to plugging the funding gap, ADB said.

Policy uncertainty over could deter investment, particularly in the case of a change of political administrations. Investors hold more sustainable assets when countries adopt climate laws, and misaligned policies reduce incentives for private investors, ADB said.

That is particularly relevant in a year that has seen elections across Asia, including in India, Indonesia and Japan. The upcoming presidential election in the U.S. is in especially sharp focus as the outcome has implications for climate-change efforts.

That’s because of the U.S.’s role as a key player in green innovation and international cooperation on climate commitments and financing, as well as a major trading partner, said ADB principal economist Shu Tian.

Policy uncertainty from a key player can significantly affect the international climate agenda, she said.

“The U.S.’s stance on climate action influences the low-carbon transition through market mechanisms, affecting consumers, suppliers, and investors,” she said. “This, in turn, could impact climate investments across the [APAC] region.”
