Answer 2

Personally, I would reckon that the majority of the LPs you refer to have little value. I know that 1, 3 and 8 at least have been transferred to CD. I must admit to never having heard of Jacob Lateiner - who is the conductor? Paul Badura-Skoda, Robert Casadesus and Richter-Haaser are not noted Beethoven interpreters so I wouldn't hold out a great deal of hope of those recordings having much value.
