I think in the good old days the letters were actually part of the keys. Nowadays the letters are usually silk-screened on.

I'm looking at my keyboard now and was surprised to find the N key, along with the right-shift and left, right, down keys are the most worn. The N hasn't disappeared yet, but the arrows are totally gone.
