Marks of value are rarely found on Greek coins, and in most cases they are indicated by the design. What we can see on the reverse of the present example are three crescents which are the three quarters of a complete moon. That is exactly what Tritetartemorion means: three times a quarter of an obol. Thus in this case, the reverse design informs the user of the coin's value.
