The first small cent was struck in a composition of 88% copper and 12% nickel. Uncirculated pieces weigh 4.67 grams, or approximately 72 grains. They have a diameter of 19 mm (modeled after the British penny) and all have a plain edge. As all were coined at the Philadelphia Mint, none display mintmarks.
Flying Eagle Cents tend to tone various degrees of brown, often a light grayish brown that is appreciated by many collectors. Finding choice, original pieces can be challenging and cherry picking is advised for collectors seeking quality examples of this popular series.
