I have a coin with a Indian woman and child it says liberty and the year is 2000 it is a 1 gold coin What is it worth?

You have a common coin called a "Golden Dollar" or "Sacagawea Dollar". It's not really gold. Sacagawea dollars are composed of .770 copper, .120 zinc, .070 manganese, and .040 nickel.

These dollars are only worth $1. There is no expectation they will be worth more in the future, so despite the fact that some people are mistakenly hoarding them, feel free to spend it.
