PIERRE, SD— South Dakota is thinking about maybe putting Mount Rushmore on its upcoming state coin, sources reported Monday. "I forget who came up with the idea, but Mount Rushmore is definitely in the running," said State Coin Selection Committee chair James Kolter. "We're also considering many other worthy subjects, from the historic birthplace of Cheryl Ladd to our oft-used highway system. It's definitely going to be a tough call." The committee has until late 2005 to decide.
