Project 19 : Mathematical Study of Coins

                                           Mathematical Study of Coins Look at the coins that you use every day. Did you know that collecting coins is a hobby called **Numismatics**?  This fascinating hobby gives us a window into the history of our country and the world. Each coin tells a story – about the era it was minted in, the leaders in power, and the technology available at the time. https://mycoincollection2023.blogspot.com/2024/05/my-mothers-coin-collection-enduring.html   World over , the size, weight, and materials used in coins have changed over the years.
