Think not about "grease" per se, (It has groove, it has meaning, and it is "The Word".), but think of congealed oil with fine particles of metal in it. When these bits of "metally oily crud" end up on a coining die, and get into the text recesses on the die, there is no cavity into which the metal of the planchet can flow, and letters seemingly "disappear". The violent motion of the die, and it is violent, eventually can shake the crud loose.

Good explanation VKurtB. Grease is sort of a generic word and can also mean the compound used when polishing dies which will give the same effect when it fills the cavity of the letters and is not removed properly.
