I want to know the answer to the following question:
Who was featured on the copper - nickel dollar?
All the background I'm provided with is that "In 2000, a new $1 coin, featuring Sacagawea, (the Sacagawea dollar) was introduced, which corrected some of the problems of the Anthony dollar by having a smooth edge and a gold color, without requiring changes to vending machines that accept the Anthony dollar.". Is that enough to answer the question?
Answer: no
