What country uses a single pound coin?
Excuse me, could you clarify something for me? The paragraph mentions a "single pound coin" being used in a country, but I'm a bit confused. Are you asking which country specifically utilizes this type of coin in their currency system? It's my understanding that the pound sterling, or simply the pound, is the official currency of the United Kingdom, and that the single pound coin is one of the denominations used there. So, based on that, I would assume the country being referred to is the United Kingdom. Is that what you meant?
