Here's a miniature Cap'n Crunch treasure chest from the 80s, not to be confused with a much better (and larger) one that was came out during the 70s. It's just a simple blue chest, about two inches long, with a small slot to slip coins into. They were packaged with a couple of paper coins decorated with Cap'n Crunch images, but those were apparently lost over the years. My chest is naked, and it can only fit three nickels.
