What is a guinea coin?
Excuse me, could you please elaborate on what a guinea coin is? I'm not familiar with this term and I'm curious to know more about its history, value, and significance in the world of finance and currency. Is it still in circulation today, or is it considered a historical artifact? Additionally, how does it compare to other forms of currency, both in terms of its physical characteristics and its purchasing power? Thank you for your time and consideration.
