When I found this artwork online I contacted the artist to see if I could use it. They were more than happy to let me. I worked with another artist to colorize the artwork and add some additional elements there were not in the original artwork. I took the theme to the back of the coin and think we have another great series for your collection.
The first is 'Earth': Mountains in the wings and other earth features along with greens and browns make this a beautiful coin. The is the easiest one to find the dragon in, the rest will be a bit more difficult.
