So just today I was working and next to the computer was some loose change from last night and I started fiddling with these coins when I realized I had a dollar, a 50 cent, one 20 cent and two 5s. Out of nowhere, I thought of stacking them then something occurred to me – If I decide to stack these based on their monetary value, putting the 5s at the bottom, it’s not gonna be a firm stack and any slight movement would send the stack falling. So I did what you'd probably do with your loose change when you stack them and I stacked them based on their size starting with the biggest coin and up to the smallest – 50c, 20c, $1 then the two 5s. You might think this is a no-brainer, right? Then I realized something outstanding!
