Hello, welcome to C.T., as you can see, not everyone plays nice here. Politeness, or Patience are not required for membership. Sorry, I don't think you have a dd there, but keep looking, they are out there.
Denver over-used their dies in 1992 resulting in what we call DDD (Die Deterioration Doubling). It is a common occurrence and generally not worth a premium above face value. Your coin exhibits classic DDD.
