What is the value of a 1999 US silver dollar?

It's important to know what kind of coin you have. If it's a large (40 mm) silver coin struck for sale to collectors and investors you have what's called an American Eagle coin. If it's small (26.5 mm) with the portrait of a very severe-looking woman on the front and an eagle landing on the moon shown on the back, it's a Susan B. Anthony dollar and is made of copper-nickel rather than silver.
