Recently, two gold coins estimated to be nearly 2300 years old were found in a swamp, with one coin being a stater weighing 7.8 grams and the other a quarter stater weighing 1.86 grams. According to Swiss archaeologists, this find is significant as it belongs to a small group of just over 20 known ancient Celtic coins originating from Switzerland, shedding light on early currency practices in Europe.

The term 'stater' is derived from ancient Greek coins, with evidence suggesting that mercenaries in continental Europe were increasingly paid with Greek coins by the late 4th century BC. This paved the way for the development of Celtic coins, which were inspired by these Greek originals in the early 3rd century BC. The gold staters found date back to the reign of Philip II of Macedon, the father of Alexander the Great, adding a layer of historical significance to this discovery.

On the coins, the obverse features a profile of the Greek god Apollo, while the reverse shows a chariot drawn by two horses. However, experts noted that these newly discovered coins have unique characteristics that differ from their Greek counterparts, indicating regional adaptations in coinage. This find not only enriches the historical narrative of currency in the Celtic world but also highlights the interaction between Greek and Celtic cultures during that period.
