1. Coin: This is the most common meaning and refers to a piece of metal used as money. This is the direct translation of the French word.
2. Corner: This meaning is less common and refers to a sharp point where two lines or surfaces meet. This is a much older meaning of the word "coin" in English, and it is related to the Latin word "cuneus," which means "wedge."
So, depending on the context, "coin" can mean either a piece of money or a corner.
