Proof coinage

Proof coinage is like when you make a very special drawing and you want to show it to someone, but instead of a drawing, it's a coin. When people make these special coins, they take extra time and care to make them super shiny and pretty. They also use high-quality materials, like really shiny metals, to make the coin look extra special. These coins are made just for collecting, and not for buying things with. So, if you ever see a coin that looks extra shiny and pretty, it might be a proof coin!
