The Silver coin is a common currency in many lands. They often bear the face of an important individual of the lands they are minted in.
Graham noticed a shiny silver coin lying forgotten on the street near a broken wagon in the Serenia towne, likely left there by one of the Baker Bros. who was working on the wagon. He picked up the common silver coin from the street, and was later able to use it to buy a nice custard pie.
Behind the scenesEdit
While there is no exact way to tell who is on the coin, it is likely to show the image of George IV, Priscilla or Kenneth the Huge, which were the sovereigns of Serenia. Listed as the "Silver Coin" in the Nintendo Power article.
