Yes, I know what you mean about the stocking stuffers. I ran into a spell a couple of months ago where I found one or two rolls in every $200 searched with a nickel in place of a quarter. The size differential is so large that you know it has to be deliberate. I did run into one moron, though, who was adding a nickel to a quarter roll, but forgot to remove a quarter. At least I came out ahead on that hunt!
