Sharp strike seems to be a component of grading for many series. Cameos, ultra cameos, etc. are grades assigned to the first coins off the die, which imparts the strongest strike.
For circulation coinage, DMPL for Morgans seems to me to be a type of "cameo" for business strikes. Merc dimes can be full-split bands, Jeffersons can have full steps, etc. I'm not familiar with the + and star grading additions, but I would suspect sharpness of strike are a component of those lofty designations.
I wonder how many MS70's are floating around that were Struck Through Grease.
