I've been saving bullion nix for many years. My daughter is in college now, but when she was very young, I taught her about saving nix, too. I made up a clever (?) name for the large plastic bucket I still use today for bulk nix (before bagging and storing).
I call the bucket "NOFTSON." That stands for Nickel Only For The Sake Of Nickel. Nothing collectible winds up in the NOFTSON bucket. Was fun to have my daughter come home from school or after being with friends saying, "Dad, I've got 2 more for the NOFTSON bucket." It's a word she remembered very well and couldn't
understand why everyone didn't have one in their house.
