I like garage sales. I always find it sad seeing people's who have passed away having what they thought so much of just being picked over and often just thrown away.
Find someone who really wants what you have and just give it to them.
Of course if it is Truly a collectable of some value find a buyer.
As someone who recently went through the same thing in order to move. I found once something was gone I didn't give it another thought. All that stuff becomes a burden of sorts.
Truth is, you don't really care much about it.
