In such a small space no bigger than the size of one section of your thumb, it can store 50 - 100 coins! The opening on the top is of common size, but when a coin taken in, and jingles down the funnel to bottom, the coin will be only of a quarter size miraculously. However, when you take it out, the coin will return to original size.
