Thank you for starting this message and sharing on the 'what if's'. It gives us food for thought on a subject matter that will happen to all of us...Just a matter of time..
I too have 2 sons. My plan is to sell the bags to travel the world before I die. If I drop dead all of the sudden, they can do whatever they want with my bags. I don't care. I'm in heaven.
Although my children have no interest in my H collection I've made sure they are well aware of its value. Consignment or one of the internet auction sites would offer a solution to downsizing/disposal etc.
