Seems a common factor in these stories is that people don't leave a guide to what they are and what they are worth.
Wow that's really cool, I seriously believe early Aus pennies will be worth something one day. ( belief or prayer actually ? )
How I was future Proofed as a kid; Everytime I started a sentence with "I want..." I got a thick ear before I could get any other words out.
Cheers, that made me laugh out loud. I 'future proof' my kids not by leaving them a scooby snack when I die, but rather educating them on the way the real world works whilst they're still young and eager to learn.
