The horizontal lines are planchet striations formed during the rolling of the metal stock sheet. The following photo illustrates the four stages of a copper-plated Lincoln Cent. It is a bit hard to see on the plated planchet but you can clearly see the same striations on the unplated zinc blank and planchet. When a coin is struck, the striations are almost always obliterated but they will be preserved when a coin is struck through a heavy layer of grease.
