Plain edge. A coin with a plain edge has no devices or lettering. It may be uneven if a collar is not used to hold the planchet and the coining press. If the coining process employs a collard during the striking process, the edge will be smooth and even around the entire circumference of the coin.
Reeded edge. A coin with a reeded edge has a series of evenly placed vertical grooves around the entire circumference of the coin. The collar has these grooves milled into it and are imparted into the edge of the coin. During the striking process.
Lettered edge. Lettered edge coins have words or symbols incused into the edge of the coin. These inscriptions may include the date meant Mark denomination, a motto or other things.
Decorated edge. Coins with a decorated edge may have different designs impressed into the edge of the coin. Flowers, vines, bars, and swirls have all been used to decorate the edges of coins from around the world.
