Which banknote is counterfeited most often?

? The most commonly counterfeited banknotes worldwide are:

• The US $100 bill – the top target outside the US. It’s widely used in international transactions and large purchases, making it especially attractive to counterfeiters.
• The US $20 bill – most frequently counterfeited within the US. It’s a smaller denomination often used in everyday retail transactions.
• The €50 and €100 notes – popular targets in Europe. Despite being among the most secure currencies, counterfeiters still go after them.

Criminals don’t usually fake the biggest bills – they fake the ones that:

• are often accepted without checking,
• are used daily,
• can be slipped into circulation at markets, gas stations, and shops.

? Tip: always check high-value bills against the light, by touch, and using their security features. One minute of attention can save you from financial loss.
