Anybody buying this collection is almost certainly going to be a dealer. If they opened up the boxes and went through them, they would probably end up with maybe 5% of the records being worth 95% of the value of the collection. Otherwise, they would be guessing (like buying a sealed storage unit). They would have to see at least a few random boxes and extrapolate what might be in the other boxes. When I sold my collection earlier this year, it was 15,000 records and took over 250 boxes. Of course the difference was the dealer helping the buyer knew my collection and was the one coming to me to see whether I was interested in selling.
