Interesting fact
The Tetradrachm - Sparadokos coin was used as a form of currency in the Kingdom of Odryssa, which was a Thracian kingdom located in the northern part of the Balkan Peninsula, present-day Bulgaria. The coin was made of silver and weighed 17 grams, which was a significant amount for a coin at that time. It's interesting to note that the coin's design featured an image of a mythical creature called the "Sparadokos," which was a symbol of the Thracian people and their connection to the natural world. The coin's design and the use of silver as a material reflect the advanced craftsmanship and economic systems of the Odryssian kingdom during that time period.
