I think we all need to acknowledge at least two people thought there was something of value in this lot.
Whether they have lots of disposable income and wanted to spend the winter attacking those pages one stamp at a time, or for resale, or cuz they think there is a decent chance of a rare variety/grill/shade, whatever.
I wish them well and hope they find plenty of value in their lot; regardless of which currency they are measuring it in.
It would also be nice to know what it was they saw
