There is no "AT" or "NT". We only have "market acceptable" or "not market acceptable.

<< <i>A different way to think of your question is to wonder why there are eleven grades for mint state coins (MS60-MS70) while there are nineteen grades for circulated coins (PO01-AU58). >>
Good point.
I forgot AU-53.

I wanna get the first AU-51! I bet it would sell for a ton of money!

Well, technically there is only 1 more grade. 50-59 for AU and 60-70 for MS. Because wear is uneven and never in exactly the same way it has been standardized to lump the AU in to grade ranges. With MS there is no wear only damage from stacking or being hit by other coins in a bag. Much easier to count marks than it is to define AU wear to a number.
AU53 is also used quite a bit since 50-55 is such a big range. I Have a few 53's.
