What were the first 50 yen coins made of?
As a keen observer of cryptocurrency and finance, I often find myself delving into the historical roots of monetary systems. A question that has always piqued my interest is the material composition of the earliest 50 yen coins. Given their significance in Japan's monetary history, I'm curious to know - what were the first 50 yen coins made of? Was it a precious metal like gold or silver, or was it a more common material like copper or nickel? Understanding the material composition of these coins could provide insights into Japan's economic and cultural landscape during that time.
