Why do coins have an image on each side?
Could you please elaborate on the reasoning behind the inclusion of images on both sides of coins? Is there a historical significance or a functional purpose to this design choice? Have there been any instances where coins lacked images on either side, and if so, what were the implications of such a design? Additionally, are there any cultural or aesthetic motivations that contribute to the selection of specific images for coin faces? I'm curious to understand the intricacies behind this age-old tradition.
