Is the 1-70 grading scale applied differently for US, World and/or Ancient Coins?

I have no information on this question, however I presume that the 1-70 scale can be applied the same way to US and World coins. Many examples of these coins in all conditions (poor to high grade mint state) exist and can be inspected. Further, production technology at the mints that produced these coins are probably similar for any given time period.
However, applying the 1-70 scale to ancient coins strikes me as odd. I recently saw a number of slabbed ancient coins (Roman, etc.) over 2000 years old, graded F-12, VF25, EF40, etc.
I know little of ancient coins but find it hard to believe that human graders of today (say 25-55 years of age) can determine what a coin made over 2000 years ago should grade at. Are there examples of these coins which are MS65 or higher (thus representing what the coin looked like when newly minted so long ago) that graders can compare submitted coins to? Do TPG's have grading sets for ancient coins with examples ranging from 1-65+ that graders can compare submitted coins to? Do graders and TPG's have information on the production technology used by peoples in ancient times so that they can understand what a 2000+ year old Roman, Greek, Iberian, Phonecian (SP) or other coin should look like the instant it was struck.
Your thoughts and comments please.
