Whats your oldest personal possession

A box full of old Photographs of my Family.Not many of my Dad( Died in accident) when I was 14 or my Mom who died of heart disease when I was 18...both 38.. Had to raise my 4 younger sisters with my ***** 1st wife.I almost digitized them once but nothing like looking at an old Black and White Photo. To me memories are better than possessions even tho I would like to have some of my old Tonka Trucks. :)
