Change Separator Pockets

Depending on your country's currency system, you would have about 4 big loose pockets, all lined up in a vertical line. Their bottoms are to be just inside the elastic opening of the pocket below, the whole thing resembling a 2D version of stacked disposable cups. Each bottom of the pocket (exept the last one) would have one or two rigid slits that let coins of sertain diameters pass. The sizes of the slits for each subsequent pocket should (naturally) be smaller than the last one. When the cashier gleefully gives you a mountain of change, just smile back, put the coins in the top pocket, and jump around. soon, the pockets will separate your useless pennis* with those shimmering quarters*. So when you need a certain coin, you will always be able to take the right one out. at the first try. There would be numerus design options for this avant grade fashion. Labeling each pocket according to the coin type in a big red font would be just the thing to impress your date. Your sophisticated peer would enjoy the word play when you explain that "Pennies" goes through "slits." Above all, you would not have to fumble with all four* types of coins while the other hand is busy scratching your nose.

* For people who are not using USA currencies: well, too bad! I'm not going to waste my precious energy imagining some foregin coins fitting some imaginary gaps.
