What is the value of a 1918 silver dollar?

Answer 1

You need to supply much more information - mint mark, condition, and most importantly why you think it's mis-struck. If you're referring to the spelling of the word TRUST in the motto In God We Trust, that is not a mistake. There are several other threads on this site explaining the use of the Roman alphabet on coins of the 1920s. It only had 24 letters, and what we write as U and J were replaced by V and I respectively.

Answer 2

The U.S. did not mint any silver dollars between 1905 and 1920 inclusive. Please check your coin again and post a new question.

Answer 3

It depends on what you call a misprint?, please be more specific and post new question.
