So-called red examples are found in a wide range of colors, typically toned in a more monochromatic manner than silver, with different shades generally appearing in specific minting periods. Whether it be the white gold hues of the copper nickles, the many shades of mint gold of the early bronze coins, or the vibrant reds, oranges and tans of the later dates, a type set of every color variety in this series would include more coins than a date set.
        Usually only associated with silver coins, toning exists in its own unique way on Indian cents.
