Black's Law Dictionary
A mark put upon a thing to distinguish it from another. Originally and literally, a mark upon the ear; a mode of marking sheep and other animals. Property is said to be ear-marked when it can be identified or distinguished from other property of the same nature. Money has no ear-mark, but it is an ordinary term for a privy mark made by any one on a coin.
