I believe these are all old server ups, and the price will vary depending on who you talk to. I did see a music stand on a safe priced at like 350 mill not sure if it sold or is still there.
I would venture an opinion that the music stands have a value of 175 mil to 225 mill. The sheet music by its self is more difficult to acquire and would estimate that at 200 mil to 300 mil.
