What is coin collecting?
Could you elaborate on the concept of coin collecting? I'm curious to understand the motivation behind this hobby and its significance in the world of numismatics. Specifically, I'm interested in knowing how it differs from simply collecting currency as a means of investment or saving. Does coin collecting involve a particular focus on rare, historical, or artistic coins? What kind of research and knowledge is required to become a serious collector? Finally, what are some of the most prized and sought-after coins among collectors? Thank you for taking the time to answer these questions.
