10 Interesting Facts About Banknotes

10. Nowadays, banknotes are counted, sorted, and verified by banknote processing systems, using sensors to evaluate fitness and authenticity. Sensors can collect 25 MB of data from each banknote, using it to detect soiling and deterioration, thinning of the material, and tears held together by sticky tape

9. When banknotes become heavily wrinkled, damaged, or dirty, security can’t be guaranteed. Banknotes are therefore checked and replaced regularly: indeed, each year, a staggering 170 billion banknotes are shredded and replaced with brand-new ones, hot off the press.

8. Andy Warhol’s “Dollar Sign” series from 1982 has become an immediately recognizable icon depicting the moment when art intersects with money and commerce. At the time they were made, the signs reflected Warhol’s fascination with money as a symbol of status and power. Nowadays, his dollar-sign paintings are worth tens of millions of dollars.

7. Throughout their lifetime, banknotes have to be resilient. Low-value “market” notes, in particular – the currency that passes through our hands many times a day – need to be robust. Banknote paper must therefore meet standards in special stress tests, including being exposed to 120°C hot air for 30 minutes; put through a washing machine cycle at 95°C and 900 spin revolutions per minute, and enduring five minutes of pressing under a 160°C iron. Once the paper has survived that, the banknotes are ready for anything we can do to them.

6. Back in 1917, Romania’s 10-bani note that was produced as part of a war series by the country’s Ministry of Finance is the smallest banknote ever to be produced in the world. Measuring a miniature 44 mm by 33 mm, the green banknote featured King Ferdinand I on the front and the coat of arms of Romania on the back.

5. The costs of producing paper money depend on many factors, such as the size of the banknote, its security features, and the production quantity. According to the German Federal Bank, a euro banknote costs on average 8 cents to produce, while in the US the Federal Reserve says that the cost of printing paper money ranges from 7.7 cents to 19.6 cents per note.

4. Cash is sustainable. For cotton banknotes, mints use the waste from the textile industry – short-fiber cotton that can’t be used for clothing or furnishings and would otherwise be discarded. Meanwhile, the new Philippine peso is as organic as they come, made of 80% cotton and 20% local abacá banana hemp, which is also used for tea bags, cigarette paper, sausage casings, and industrial filters.

3. Fijians are passionate about rugby union, both the traditional 15-a-side format and 7-a-side. The national 7-a-side team, known as the Fiji Sevens, is one of the most successful in the world, winning multiple World Rugby Sevens Series and Rugby World Cups as well as gold at the 2016 Summer Olympics in Brazil. The Republic of Fiji created its first-ever $7 bill after the Olympic success, honoring the team by printing two million of a special-edition banknote featuring the players.

2. Many countries have printed gorgeous images of wildlife on banknotes – from the dove and palm leaves on Ethiopia’s new 200-birr note to the renowned African fish eagle found on all of Zambia’s kwacha notes, to elephants, lions, and buffalo on South African rand banknotes. So, what’s the most popular animal to feature on a banknote? No great surprise to find it’s the bird – with the king of them all, the mighty eagle, featuring on no fewer than 41 currencies around the world.

1. One of the rarest and most sought-after pieces of American paper money, the Grand Watermelon $1,000 banknote from the 1890s sold at auction in 2018 for a record-breaking $2.04 million. Only seven such notes are known to exist, three in private collections. Despite its playful name – which refers to the design of the zeros on the note – the Grand Watermelon has become a world-famous icon of American finance history.
