Selected title: Die Number
Explanation: Usually a small mark in the form of a number on a die, and therefore any coins struck from it, to show which die produced the coin. Probably used in experiments to determine the best form of treatment in the production of dies. Dies are expensive to produce, but can frequently break or wear causing delays and extra cost in production of coins
