What is the third side of a coin called?

• edge:Most don't realize that there is more to a coin that than heads or tails. The edge, which has ridges on quarters and dimes, is the third side of the coin. The heads side of the coin is the obverse side. The other side, the tails side, is the reverse. Add in the edge, and a coin has three named sides. There are also two rims that encircle the diameter of a coin. This is the slightly raised part of the coin that goes around the coin over the edge. The ridges around coins are reeding or grooving.
