The only dollar coins struck by the U.S. in 1981 were Anthony dollars for mint and proof sets. None were released for circulation. Also, the coin was never struck in silver; it was always made out of the same cupronickel "sandwich" that's used for dimes, quarters, and halves.
If your coin is from a mint set, it's worth about $2.00
If your coin is from a proof set, it's worth about $5.00 if it's a Type I coin, but could retail for $140-150 if it's a Type II. See the attached links for pictures.
A real silver dollar has a $25.00 value just for the silver.
