👉 A coin's fluid, also known as its minting fluid or die fluid, is a liquid substance used during the coin-making process to lubricate and cool the dies (molds) that create the coin's design. This fluid typically consists of a mixture of oils, waxes, or silicone-based compounds, which helps prevent the dies from sticking to the metal plates and ensures a smooth, consistent impression of the coin's intricate details onto the coin's surface. After the coin is struck, the fluid evaporates, leaving behind a clean, precise imprint that defines the coin's appearance and quality.
