I purchased one of the 2016 Mark Twain coins for my grandson. He has a fascination with all things frogs. Now that he is understanding money and collecting I figured it was time to help him learn that he can easily combine his interests. We can dive in together to learn more about Mark Twain and his stories starting with that famous Frog. My grandson asked the question "How many coins have Frogs on them"? Good question already! I told him we could ask our ANA Community for help with the answers. So, does anyone know of other coins with Frogs? Thanks for your responses in advance!!!
