how much is a morgan 1 dollar coin worth?

Answer 1

Between $9 and several hundred thousand dollars.
Your question is extremely vague. There are many variables to consider when evaluating a silver dollar: Date, mint mark, and condition are the three main ones. A common date, such as 1921, in circulated condition, will be on the extreme low end of the value range. A rare date in pristine uncirculated condition will be on the high end.
I need more information (Date? Mint mark, if any? Condition?) to intelligently answer your question.
