When I hit 50 years old and my son had moved out, my wife and I decided to move out of the family home that was 15 rooms with 5 baths and 3 stories to a smaller home with one story as the stairs were getting hard on her. Moving to a 6 room house meant getting rid of 50 years of accumulated souvenirs, collections, trinkets, old clothes and assorted junk.
My attic was full of my collections of old toys, WWII bubble gum cards, old comic books, Playboy magazines (I read the articles) antique radios, and many other objects. I decided that I had enjoyed all of them for many years and instead of saving them for more years just stuffed in the attic, I would sell them to others to enjoy. At first we tried to decide to who to give them to but decided against that because we knew from experience that when someone gets something for free, they never care for it as much as someone who uses their hard-earned cash to buy it. So I sold everything on eBay in bits and pieces for the next year.
I had over 1000 happy customers and no complaints and received a sizable amount of cash doing so. Sometimes I say to myself, I wish I still had my so and so, but then I realize that someone else is enjoying it and it was just in a box in the attic anyway. I still have most of my 2100 beer can collection in boxes in my garage and I refuse to believe they are worthless because I sold the 100 or so valuable ones and the rest aren't even good for scrap because they are steel not aluminum. I have used a couple of hundred of duplicates that I saved for trading as targets but can't bring myself to shoot the ones in my collection.
