I remember those types were available at every bank as a freebie with the banks name on it. Like these.
^ We used these in elementary school for hopscotch. We'd rub them with wax to increase the sliding ratio. The older they got, the stiffer the coin purse, the farther and smoother they'd slide. I don't recall ever using it to hold coins lol. Speaking of wax, we'd also use used smashed drink cups (covered in wax) and rum them on the slide for increased speed. Worked every time.
