Aloha Ken:
 
To get a number count of 'obsolete' USGS topo series and to see their
spatial arrangement and location you may want to consult WAML
Occasional Paper #10, "Map Index to Topographic Quadrangles of the
United States, 1882-1940".

Greetings,
Regarding Ken Rockwell's inquiry, I don't have the statistics, but
perhaps the following two publications may be of some help in
providing that information.  At the very least, the books may serve
as a checklist and will give you an idea of how complex your
retro-conversion/reclass project will be!
 
     Map index to topographic quadrangles of the United States,
     1882-1940, by Riley Moore Moffat. c1985 (WAML Occasional
     Paper; no.10).
 
     A cartobibliography of seperately published U.S. Geological
     Survey special maps and river surveys, by Peter L. Stark.
     c1990 (WAML Occasional Paper; no.12).
 
Aloha,
