Most people think collecting currency is just about old money. It's not. It's about holding a piece of history that governments are actively destroying.

Every year, central banks pull billions of notes out of circulation and shred them. The ones that survive in good condition become rarer by the day.

Here are 5 banknotes every serious collector should have in their portfolio:

1. Zimbabwe 100 Trillion Dollar Note (2008)

The largest denomination ever printed. A symbol of hyperinflation that's now worth more as a collectible than it ever was as currency. Prices have 10x'd in the last decade.

2. Iraqi Swiss Dinar (pre-2003)

Printed in the UK, these were replaced after the invasion. Sharp, detailed engravings that modern printing can't replicate. Supply is finite and shrinking.

3. Soviet-era Ruble (1961 series)

Clean design, historical weight. These circulated across 15 countries that no longer exist. Finding uncirculated specimens is getting harder every year.

4. Brazilian Cruzeiro (hyperinflation era)

Brazil changed its currency 8 times in 50 years. Each denomination tells a story of economic chaos. Complete sets are becoming nearly impossible to assemble.

5. Any pre-independence African note

Colonial-era African banknotes are massively undervalued. Low print runs, fragile paper, and growing demand from collectors across the continent.

The best time to start collecting was 10 years ago. The second best time is now.
