Greaser !
Not grease, overpolished die. That part of the design is very shallow with the relief just slightly higher than the field. With some polishing of the die it become the same level as the field and the roof "floats". If there was grease in that location it would simply get pushed down into the deeper recesses of the die on either side during the strike.
