I remember when many of the Classic Records archives were hawked on eBay, maybe ten years back, a test press 45 set of the Zeppelin BBC sessions went up. I forget how much it ended on - it wasn’t cheap but I was a little surprised it didn’t go higher. Silly listed prices on Discogs and similar can train people to think stuff is much more “stupid valuable” than it actually is.
But $750 for the whole catalogue is cool!! 😎
