Ya never know the real value but ask my wife. She will tell ya its all trash. Better still would be posting a story of how you finally used that item hidden in your garage after so many years. Here's one...
Had to stabilize with four points a heavy crate at least 1" above a slab. Told my boys to go to the garage corner and dig out the four disk brake disks from our 1978 Mercury Grand Marquis station wagon. We put them on the corners of the crate and they worked perfectly. My Boys said... Dam Dad!
Here is another one. Am I ever going to use that Ammo Can with desiccated Wright's Stain, Giemsa Stain, or my desiccated Gram Stain set. Hopefully not... But am I going to throw them away...?
