It sounds like you have a generic silver round with the Mercury dime design on it.
As far as being fake, the design itself doesn't make it fake. I have 2 similar ones with the Buffalo nickel and walking liberty designs on it.
Does yours say 1 oz silver anywhere? If it does run a magnet over it and if it doesn't stick it should be silver. Since its not a mint coin you only need to be concerned if its made out of what it says it is
