My grandfather was a Julliard graduate and later conducted at Radio Music Hall for many years. His name was John Dosso. My mother is moving out of her house to mine and I found my grandfathers records. I will just list the names of the top four I took out of a box. They could not have been played in 50 years and look to be in great condition:
Worlds Greatest Operas In six parts, part five in French
                    FUAST (GOUNOD) act IV
                    March and Soldiers Chorus
Red Sseal record
                    RCA Victor
                    13790-B
                    FUAST-SALUT, DEMEURE

Are these worth anything?
