Query: Works fine and fast

It's true that sometimes at the top of the column a coin or two fall into the bowl below, but that's very easy to remedy. As long as you have the cylinder full (flat even to the top), it's the right amount for the coin sleeves. I counted the first time to be sure. And it's sure faster than doing it by hand, as I used to.
