You're talking about the "fine-sort program," where the bank does the sorting so that the Federal Reserve Bank doesn't have to.

I think it's time for Tom Scully to eat a little humble pie. He keeps pounding on the fine-sort program, like that explains how it is that the money order hasn't any bank stamps on it. Well guess what, Mr. Scully... the fine sort program wasn't established till 1979. It was first tested in a pilot program in 1970 at the Washington-Baltimore Regional Check Clearing Center. In 1974 it was implemented at the New York FRB only. And in 1979 the program was expanded to all FRBs.

I don't think those documents say what you seem to think they do. In the 1970 document, the term "fine sort" appears in the article titled "The Washington-Baltimore Regional Check Clearing Center." It clearly implies that the new innovation is the concept of the clearing center, and mentions that fine sorting may be done by member banks (including any member FRBs) before sending the items on to the clearing center. It's possible that they introduced the method of fine sorting along with the establishment of the center, but if they had, I would have expected a great deal more about this wonderful new sorting method. In any event, it does not claim that fine-sorting is a new process invented just for the Clearing Center. The bulk of the other articles dwell on updates to policies regarding the receipt and handling of pre-sorted and unsorted items, and do not say that fine- or end-point sorting was anything new to be implented and do not state that fine-sorting was introduced in 1970.
