The different between specimen and normal bond was that the normal one is in one piece with the front and back page and the specimen one was printed in two different pages with the front and back side. Moreover, it was tied with the specimen mark in the specimen bond. It is a real bond with specimen marking that is a geniune issue. I guaranteed all my bonds are 100% original.
