Money is one of humanity’s most striking inventions. But do the banknotes we carry daily really consist of "paper"? Here’s a comprehensive guide filled with surprising details about the materials, production processes, history, and future of banknotes…
Why Are Banknotes Made from Cotton?
Despite being called “paper money,” the primary material used in banknotes is cotton fibers. These fibers undergo special processes to be transformed into a thin, durable, and water-resistant surface. For example:
- The US Dollar is made from a blend of 75% cotton and 25% linen.
- Euro banknotes use pure cotton, while the Japanese Yen uses fibers from the “mitsumata” and “kozo” plants.
Why Is Cotton Preferred?
✅ Durability: Cotton-based banknotes have four times the wear resistance compared to regular paper.
✅ Security: Security threads and watermarks can be easily embedded between cotton fibers. These embedded features are critical in protecting against counterfeiting. Scientific studies have shown that specific security fibers are capable of being viewed under different types of light, making them nearly impossible to replicate.
❌ Weak Point: Cotton can mold in humid environments. This is why polymer alternatives are increasingly popular in tropical regions.
Interesting Fact:
In Turkey, the 200 TL banknotes are produced from local cotton and special chemicals. Some of the cotton used comes from fields in Şanlıurfa!
The Polymer Banknote Revolution: The Age of Polymer Money Begins!
Australia launched the polymer currency trend in 1988, and today it has spread to over 50 countries. The UK switched to fully polymer banknotes in 2021, while India printed special polymer notes in 2022 to mark its 75th independence anniversary.
The Hidden Facts About Polymer Banknotes:
- Material: They are made from BPA-free transparent polypropylene. This material is not only durable but extremely resistant to wear and tear. Scientific studies show that polymer notes can last up to twice as long as paper notes.
- Production Cost: One polymer banknote costs twice as much to produce as paper notes (e.g., 20 AUD costs 0.20 AUD to produce).
- Environmental Impact: Although recyclable, the production of polymer banknotes has a carbon footprint 30% higher than paper money. However, the extended lifespan of polymer money reduces the need for constant replacement, thus offsetting some of the environmental cost.
Why Are Countries Choosing Polymer?
- Longevity: In Canada, polymer dollars last 8-10 years, while paper dollars only last 2 years. This remarkable durability reduces the frequency of printing new money.
- Hygiene: In 2020, Singapore announced that plastic notes have a lower risk of harboring viruses after the Covid-19 pandemic. Studies by the World Health Organization (WHO) support that polymer notes do not support microbial growth as much as paper-based currencies do.
Critical Issue: Polymer banknotes melt at temperatures above 140°C and can leave permanent marks when folded in a wallet! Although they are better at withstanding moisture, they still have limitations when it comes to high heat.
Revolutionary Technologies in Banknote Production
- 3D Security Thread: This thread, used in Euro banknotes, displays holographic images that change with the angle. This feature is nearly impossible to replicate and adds an additional layer of security.
- Nanoprinting: China’s new 100 Yuan notes feature designs printed at one-thousandth of a millimeter thick. Nanotechnology is being employed to make intricate, microscopic designs that can’t be seen with the naked eye.
- Carbon Dots: In Switzerland’s Swiss Francs, microscopic carbon particles glow under infrared light. These nano-sized particles are used for identification and detection, and they’re effective even under extreme conditions, like UV light or infrared cameras.
- Tear Resistance: Polymer strips added to Turkish Lira notes make them resistant to over 5,000 folds, ensuring the currency withstands heavy usage in everyday transactions.
The Most Fascinating Security Feature:
In Canada’s 100 CAD banknote, a real moon surface image is embedded using laser technology. This high-tech feature makes the Canadian hundred-dollar bill one of the most innovative and secure notes in circulation.
Strange Materials Used in the History of Money
- Leather Money (China, 200 BCE): Emperor Qin Shi Huang issued currency made from white deer leather. Leather was a durable and flexible alternative to metal and early forms of paper money.
- Salt (Ethiopia): In the Middle Ages, salt blocks called amole were used as currency. Salt was vital for preserving food and had a significant economic value at the time.
- Coconut Shell (Maldives): In the 13th century, cowrie shells were used in trade. These shells were seen as valuable due to their rarity and beauty, representing early forms of commodity money.
The Tragedy of the First Paper Money:
In the 7th century, China issued paper money made from mulberry bark. However, due to hyperinflation caused by an overabundance of printed money, the paper currency was abandoned within a century!
Tips for Extending the Lifespan of Banknotes
- Avoid Folding in Your Wallet: Polymer banknotes retain fold marks, which can affect their aesthetic value. Especially polymer notes, when folded, can leave permanent marks, so it’s essential to store them flat.
- Keep Away from Heat: Paper banknotes deform at 150°C, while polymer notes deform at 120°C. High temperatures can cause discoloration and damage to the surface of the note. Avoid hot environments to preserve the banknotes.
- Wash Carefully: Clean polymer banknotes in water that doesn't exceed 40°C. Otherwise, the surface of the banknote may get damaged. It’s safer to use a damp cloth for cleaning rather than washing them.
Shocking Fact:
According to data from the Central Bank, 150 million banknotes are destroyed annually in Turkey due to wear and tear! This figure highlights the high frequency of use and wear.
The Currency of the Future: Digital or Biodegradable?
- Bio-Currencies (In Testing): In the UK, prototypes of banknotes made from mycelium fibers (the root structure of mushrooms) are being tested. These notes are expected to be environmentally friendly and biodegradable. Mycelium fibers have also shown promise for use in packaging and other sustainable materials.
- Flexible Screen Notes: By 2030, digital-physical hybrid notes with QR codes and real-time currency updates are planned. These notes will combine financial information with physical currency for enhanced functionality. Such smart currencies could interact with mobile devices and enable instant updates on the value of money.
- Central Bank Digital Currency (CBDC): In China, by 2023, 1.8 billion digital Yuan were in circulation. CBDCs, issued by central banks, could drastically transform global monetary systems, especially with potential blockchain technology to enhance security and transparency.
Survey Result:
67% of young people say, "I will no longer carry physical money," while 89% express concerns, stating, "I am afraid digital currencies can be hacked." These results indicate growing concerns over the security and privacy risks associated with digital currencies.
Final Thoughts: The Evolution of Money and Humanity
Money is not just a means of payment; it is a reflection of technology, trust, and culture. Over time, as technology advances, so does money. Perhaps in the future, we will use virtual currencies that operate through retina scanning, rather than gold-colored polymer notes. Despite the shift to a digital world, many of us still find value in the physical touch of currency. So, what do you think? Should money become fully digital? Or will the physical feel of cash always hold its value?
