How much is a pure 1990 silver dollar worth?

Answer 1

Assuming you have a large (40 mm) coin with the famous Walking Liberty image on the front and the words .999 fine silver on the back, it's a 1-oz bullion piece whose value changes with the price of silver. Any answer posted here would be out of date almost immediately but you can find current prices at many sites - kitco.com is a good one.

Note that the $1 denomination is artificial. The coin is issued for investing, not spending and is not the same as the true silver dollars minted up till 1935.
