Its rare that an official Greek collector coin makes it to Australian shores and, appropriately. this one commemorates a theme as rare - or perhaps even rarer! The Antikythera Mechanism was discovered at the bottom of the ocean and is thought to be one of the earliest versions of an analog computer! And its early - the machine has been dated back to at least 87BC!
Depicting the largest visible gear from the ocean weathered mechanism in full colour, this official Greek silver coin is limited to just 2,000 released.
