Regarding the baseball cards, don't feel too bad. I went through my husband's MASSIVE stack, and after hours and hours and hours of inventorying them (never got it finished, but got far enough to know with confidence) there wasn't squat in the pile. While there ARE very valuable cards, I wouldn't assume your collection was worth anything.
The only things I wish I still had were items that were ruined, not given/thrown away. My Mom made a ceramic Christmas tree when I was little. You know the ones, about 16 inches tall, lights all over it. Hers was painted in a very different way from the ones you've seen a million of and it was always my favorite Christmas decoration. When my sister, lazy disciplinarian, let her
old enough to know better kids play in the formal living room, they knocked it off a table and broke it. OK, I wish I had FIXED it instead of allowing it to just be broken.
My husband also broke a really pretty small decorative plate I got while in Martinique. That one wouldn't have been repairable. But about right now I'd take the plate over him. But that's another story
