I have finally realized I collect sneakers, I have to buy a pair at least every 6 months. I am over 50 and they still give me pleasure to look at and wear, I have a watch thing as well but not as bad. What do you collect?
I buy a watch to commemorate travel abroad, if the country has a watchmaker. Bought like 50 board games since 2020...
I have a pretty good sports memorabilia collection but haven’t added much since kid was born. That and hats.
soccer jerseys although I've sold most of my collection there is a massive market for older soccer jerseys
Seriously, though - comic books, old photographs of random people/scenes, old periodicals/newspapers/magazines, colognes, etc. I like to buy stuff that "looks interesting", but mostly a lot of "older stuff" that hopefully doesn't take up much space. lol.
