The story says some coins give you luck during your life, that's my thought when I think about the original Pony coin created by Akili Amethyst in Kickstarter.
This design is inspired by the Stations of Awakening" from the game Kingdom of Hearts. This design in particular features the Equestrian Princess of the Sun, Celestia. In the background is the capital city of Canterlot, in which she resides. Symbols of daytime surround her, as well as her sister, Luna, the pony most important to her.
Also inspired by the "Stations of the Awakening" from the game Kingdom of Hearts. This design in particular features the Equestrian Princess of the Night, Luna. Symbols of the night surround her. In particular the bats were inspired by her unique cloak, which dissolves into the winged creatures for an extra-dramatic entrance. Also, featured in the design is her older sister, Celestia, who is the pony most important to her.
With the Celestia's side (real gold!), and silver on Luna's side (real nickel!).
