Denon's DL-1000A MC cartridge had an effective tip mass of 0.077mg.

Even their lower-priced DL-305 got down to 0.168mg.
These cartridges (as well as Technics 205, 305, 100) were from an era when various audio manufacturers competed with each other to see who could produce the more impressive-appearing specifications, whether the products were speakers, amplifiers, turntables, cartridges, tuners etc.
But at least in my experience, such specs don't have much relation to how a component actually sounds.
