As someone who cleans up after "ripe" deceased or those who lived alone, you wouldn't believe the kind of stuff left behind by the family.
Either they didn't know the value, or they just didn't care. I've scored several toolboxes, old cameras and media equipment (the kind hipsters love), bikes (pedal), ipods, etc. Hell, even jewelry. They were all destined for the trash anyway. The family is told to take what they want and the rest will be hauled off.
I hate doing it, but I can't count how many photo albums and shoeboxes full of photos and sentimental items I've had to throw away.
