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.
But mints around the world have experimented with Odd shaped coins for circulating and commemorative purposes. And collectors have found new and exciting coins to collect in these Odd Shaped coins.
