The straight lines are caused by the rolling out of the zinc ingots into the strip from which the blanks are punched. They are a result of the stretching of the metal and the surface condition of the rollers. New rollers create smoother surface strip. As the rollers wear the lines become more prominent.

The die scratch is just a marker to show that both coins came from the same die. The rolling lines are in different directions thus indicating that they are on the planchet and not the die.
