They are meaningless because they are an invalid arrangement of Roman numerals
The conventional conversion of 1998 into Roman numerals is MCMXCVIII whether or not the Romans themselves enumerated their numerals in this manner is open to question because the rules governing the subtractive arrangement of these numerals were introduced during the Middle Ages centuries after the demise of the Roman empire. There is strong evidence to believe that the Romans themselves would have enscribed 1998 as MDCCCCLXXXXVIII (which incidentally can be simplified to IIMM). It is interesting to note that on the building of Harvard Medical School's Library the Roman numerals for 1904 are given as MDCCCCIIII instead of the conventional MCMIV. Another example of numerals arranged in this manner are on Admiralty Arch in London where 1910 is given as MDCCCCX instead of MCMX.
Under today's rules the Roman numerals CMXLVII represent 947.
