Interesting fact

One interesting fact about this coin is that it features the Antikythera Mechanism on its reverse side, which is considered to be one of the earliest known analog computers in the world. The Antikythera Mechanism was a device used by ancient Greeks to calculate astronomical positions and predict eclipses, and its design has been called the "first computer" due to its complex gear system and ability to perform calculations. The inclusion of this mechanism on the coin adds a unique and interesting element to its design, making it a standout among other coins.
