Talk:Eisenhower Dollar

I have a 1976 Eisenhower dollar with no mint mark. It appears to be silver. It weighs 22.7 grams not the same as the silver one from San Francisco. Could it be real? It is a type two. It is not a clad dollar. There is no copper visable on the rim and appears to have the satin finish of silver not the glossy finish of the clad dollars. When I look in the red book there is a notation for a 1976 silver dollar type two, but no reference to price. It is not a proof coin.
