Depicting 4 as IIII results in a total 20 I's, 4 V's, and 4 X's for a complete clock face. You would notice that you can just build one mould with 5 I's, 1 V, and 1 X, and stamp or cast it 4 times to get all the letters you'd need. Doing it conventionally – using IV as four, you'd actually need 17 I's, 5V's, and 4 X's – you end up with a more complex mould or unused number.
