The ancient Romans would have worked out the equivalent of 1999 on an abacus counting board as MDCCCCLXXXXVIIII and then abridged it to IMM (2000-1) in written format which answers your question.
However, the equivalent of todays 1999 inRoman numerals when expressed as M+CM+XC+IX then they too become abridged to IMM as follows:-
M+CM = CMM
CMM+XC = XMM
XMM+IX = IMM
