Did you have any idea banknotes can play records, legal Pokémon coins actually exist and nickels are more expensive to mint than dimes? Blow your mind with our pick of weird and wonderful facts about money.
UK coins can be combined to reveal a secret shield design
You can arrange the newer 1p, 2p, 5p, 10p, 20p and 50p coins to reveal an esoteric shield design that mimics the coat of arms on the £1 coin. This clever feature was created by designer Matthew Dent in 2008.

Michael Ridge, a sound artist from Norwich, England hit the headlines hen he posted a video on YouTube showing him playing a vinyl record with the new £5 note.

The new Australian $5 bill can also play your vinyl collection
In fact, any crisp new polymer note can be used to play a vinyl record. For instance, Melbourne record store Northside Records recently uploaded a video demonstrating the trick with the new Australian $5 bill.

Study after study has shown that most banknotes are contaminated with cocaine. Test results suggest all UK banknotes acquire traces of cocaine within weeks of entering circulation, and up to 90% of dollar bills are tainted with the drug.
Similarly, tests show that 94% of dollar bills are contaminated with bacteria, 7% of which are potentially harmful, and scientists at New York University have even found traces of anthrax on US banknotes.
