How much is a year 2000 US one dollar coin with an Indian woman and baby worth?

It's a standard circulation coin worth $1. The woman is the famous guide Sacagawea.

Please note that I modified your question because the Word you used to describe Sacagawea is considered by many Native Americans to be a slur on the order of using the N-Word to describe someone of African ancestry.

If you weren't aware of that fact, please accept this as a learning experience.
