Copper pennies tarnish over time, taking on a brown hue. Part of the evaluation of a coin by collectors is the color and, for pennies, the color is typically broken into three categories: Red, Red-Brown, and Brown. By that standard, red cents were those that hadn't been circulated very much and were more desirable.
