A conventional horizontal misaligned die clash occurs when the hammer die is laterally shifted relative to the anvil die.  When the dies collide, the resulting clash marks are also shifted laterally.

      This 1989 cent shows a bold horizontal misaligned die clash on the obverse.  The clash is less visible on the reverse.  When the clash occurred, the hammer (obverse) die was misaligned toward the right.  As a result the incuse Memorial is shifted toward the left on the coin itself.  The hammer die was slightly rotated as well when the clash occurred.
