Summary

Got coins in your pocket?  Who needs coins nowadays?  Do as we did as a kid.  Put the coins in the box when you walk in, then you've got money at the end of every month you didn't know you had, for taking the family out to dinner for instance.
This file fits together a bit loosely, but I feel it's better than trying to file it or sand it down to make it fit tight.  Doesn't need to fit tight.
