An enigmatic coin that someone used to board a British bus seven decades ago is now entering the collection of the Leeds Discovery Centre, following the revelation that it's a bit of 2,000 year old currency from the former Carthaginian trading settlement of Gadir, in modern-day Cádiz, Spain-one of Europe's longest-inhabited cities, settled by Phoenicians around 1,100 B.C.E.
Research suggests that the introduction of monetary systems in Central Europe can be traced back to Celtic mercenaries. These men were paid for their services in Greece with coins and brought them back home with them. Around the middle of the 3rd century BC, the Celts began their own coinage, imitating gold coins of the Macedonian king Philip II (359336 BC).
The note, which features a depiction of Gorda as the model for Mexico's iconic species of salamander, went into circulation in 2021, dazzling the judges of the International Bank Notes Society, who declared it the Note of the Year. Four years later, the Bank of Mexico has released a report revealing that 12.9 million Mexicans are holding on to this note as if it were worth more than just its value of 50 pesos, or a little under $3.
