The Roman numeral for a half looks like the letter S and its Latin name is semis meaning a half. So the Romans themselves would have probably wrote out 1999 as IMM and half of this would be SM (-1/2+1000 = 999 and a 1/2)
In accordance with the rules governing the Roman numeral system, which were introduced during the Middle Ages, 1999 today is written out as MCMXCIX and halving this could possibly be CMXCIXS.
