what would be nice was if the rock & roll hall of fame or smithsonian bought this to put on display, with a jukebox like computer set up for people to listen to music of their choice from the collection.
and i doubt that there are that many shitty records. he'd been running the store since the late 60's, saving the last copy of everything that came through the store, as well as supplementing the collection with items he had purchased prior to opening record-rama (dont forget, record-rama was the solution to his fanatical collection hobby, as suggested by his fed up wife). so i doubt there are going to be 25 copies of the same barry manilow or barbara streisand records. and as he has called it the definitive archive of 20th century american music in the past, i imagine he has attempted to collect every possible release from every possible genre, no matter how obscure or unpopular it may have been, because he sees the worth of preserving the voices and sounds that record the particular histories of the context surrounding their creation.
how likely is it that he could donate the collection to a museum and write it off his taxes as a charitable donation. he wont get $50 million back, but he'll get a good large chunk that woudl hopefully be close to his asking price, n'est pas? and he would be secured in the knowledge that the whole collection would stay intact and be cared for by archival practices.
