Andreas,
I believe that they were punched with a specific die, and that there was no polishing/deburring of the edges. The small striated marks on the edges are traces left when the metal was punched out, squeezed between the upper and lower dies. As such, it is a tale-tell mark of genuineness and is extremely difficult to copy.
