One of the earliest recorded coin scandals dates back to ancient Greece around 432 BCE, during the tumultuous years of the Ancient Conflict. A large number of counterfeit owls flooded the city's markets. The fake coins had been cleverly designed to resemble the official exchange, アンティーク コイン but they were made of a cheaper, less valuable metal.
In 1643, the British Royal mint suffered a massive counterfeiting attempt when a large quantity of fake coins bearing the likeness of King Charles I and his queen, Queen Helen, appeared in circulation. The scammer, a cunning forger named Counterfeit King, produced the coins using a combination of techniques including engraving. Johnson was eventually caught and executed for his crimes.
Another notorious coin scandal took place in the United States during the late 19th century. In 1873, a group of counterfeits known as "cartwheel" five-euro notes appeared on the market. The fake notes were made of a durable paper and bore a unique design featuring a five-pointed star. They were produced by a German immigrant named Forger's Name and went unnoticed for several years before being revealed.
In the mid-20th century, Brazil experienced a severe economic crisis, partly attributed to a massive counterfeiting scandal. In 1964, an estimated 1 billion reais in fake currency flooded the market during the presidency of President X. The forgeries were incredibly realistic and almost indistinguishable from the real thing.
In more recent times, the European region was plagued by the "Berlin Gold scandal," which unfolded in the early years of the 21st century. A large quantity of gold coins bearing the German european eagle and mint marks from the European mint were found to be fakes. It is believed that the coins were produced using a combination of techniques, including engraving.
