Note: Numeral 92 is observed on almost all coins of Hyderabad. It is not the Reginal year of the state or any king or something related to the rank of Nizam or mint identification. It is the Numerical Value of the name "Muhammad". In Islam Prophet Muhammad is praised and honored, therefore Muslims do not want his name to touched with unclean hands or thrown on the floor. For this reason they represent it with the numerical sum. Muhammad: Mim + Ha + Mim + Dal = 40 + 8 + 40 + 4 = 92.
Perhaps that can help...
