There are several main reasons why most of the heads on silver coins are in profile:
1. Due to the technical difficulties in metal engraving, the space available for painting on the coins is small. The lack of fineness makes it difficult for people to draw a highly recognizable frontal portrait on the coin.

2. Drawing a side portrait on the coin is easier to achieve than a frontal portrait. The side relief portrait is more three-dimensional and the subject can be easily recognized. It's much easier.
