What is a 2000 liberty gold coin worth?

If your coin has a picture of Miss Liberty walking forward on the front, it's a bullion coin sold to collectors and investors. Its gold weight is given on the back, so multiply that by the current price of gold and add about 5% to cover the fact that it's in coin form instead of an ingot.

If it's about 26 mm in diameter, has a picture of a Native American woman and her baby on the front and a soaring eagle on the back, it's a Sacajawea dollar not a Liberty dollar and is only worth $1. It's made of brass, not gold, and there are about one billion of them in circulation.
