R - we have used Stephen M.H. Braitman, and was one of the best.
Specializes in sound recordings, registered, but in CA.
In general we have have had at least 4 major appraisals, from 25K to
over 100K recordings, and many smaller ones. When all is said and
done, after doing this for 25 years, if the collections looks at all
good, it averages out to $5 a recording. This is anecdotal, but
consistent. B. George
