Between the years 1959 to 2008, the Lincoln penny had the Lincoln memorial on the back side. However, few people know that Lincoln can be found on the backside too. The Lincoln on the backside of the penny is so small that is goes unnoticeable by many. Under slight magnification, it can be found. If the penny is tarnished, it can be made shiny by sponge scrubbing under vinegar. The acetic acid in vinegar dissolves the copper oxide leaving fresh and shiny copper.
