Odd shaped coins are just that. Odd. It is very rare to find one in your pocket change. Ever wondered why?Finding different shapes in your pocket change like a square, a triangle or a 3 dimensional shape would be quite exciting. But these shapes aren't really practical for everyday use. Imagine the inconvenience if a triangular coin gets stuck in a pocket hole. Coins with sharp edges will have more wear in their designs.Historically, it was never intentionally meant for a coin to be round in shape. When two metals at opposite ends were used to strike another piece of metal, the result was a round and thus the circular coin was born.
