What is PMD on a coin?
Could you please clarify for me what PMD stands for when it comes to coins? I've seen this term mentioned a few times but I'm not entirely sure what it means. Is PMD related to a specific type of coin damage or wear? Or is it something else entirely? Could you also explain how PMD might affect the value or condition of a coin? I'm quite interested in learning more about this topic. Thank you in advance for your help!
