What do they call the place on a coin that they put the date?

Spencer L. asks: What do they call the place on a coin that they actually put the date? It’s for a school project and my teacher said it was 7 letters long. I need you to reply A.S.A.P! Thanks for your help.

Exergue is the place where a date appears but it must be separated from the rest of the design by a device such as a line. For example, if you look at a Buffalo Nickel you will see that the date is below a line that the buffalo is standing on.  You would then say that the date is in “exergue”
