nobody ever said there weren't. The point of the matter is, not everyone can tell for sure. Most quality coins in this day and age are certified inside a slab. This states the denomination, year and the grade and establishes the authenticity of the coins. A great many people would not even buy expensive "raw" coins, especially pre 1933 u.s. gold coins. Ask anyone that collects or sells coins. They will tell you the same thing.
