What is a one pound coin?
Could you please elaborate on the intricacies of the one pound coin? As a professional in the field of finance, I'm particularly curious about its history, design, and its significance in the monetary system. Is it a circulating coin in everyday transactions, or is it more of a collector's item? What materials is it made of, and how has its design evolved over time? Furthermore, how does it compare to other denominations in terms of value and usage? I'm eager to gain a deeper understanding of this seemingly mundane yet significant coin.
