They used it back in the early 90's and then stopped.

I firmly believe in numismatics as the world's greatest hobby, but recognize that this is a luxury and without collectors, we can all spend/melt our collections/inventories.

<< <i>A useful measure of the correlation needed to maintain present standards is that the correlation between grades given by an automated system and by a human expert should be the same as the correlation between two different human expert graders. An automated coin grading system would be considered to be acceptable if, for example, two different experts agreed upon a grade 93% of the time and the automated system agreed with each expert at least 93% of the time. >>
93%
Hey, that would be a good correlation goal for just human graders, eh.
