I can sort of see buying a bunch with the hope of making a little or a lot of profit. Still a chunk of change to tie up for a maybe. As a collector/user I get more enjoyment finding things one at a time, like yesterday, was in a here to fore unknown junk shop, got a chrome combo end wrench, Wizard, from the now gone Western Auto store. Had one in town when I was a teen, couldnt buy much, but enjoyed looking at their tools. Same series as the other five Wizards I own.
