You Win

This can be a mental trick or can be presented as a beer table bet and we are shure: You and your audience will have fun. You borrow a coin of different value from each of the "volunteers" around you. So you get a one, two, five, ten, twenty and fifty cent coin, as well as a one and two euro coin. But before that, you give a prediction in a sealed envelope to a control person. The betting is very simple: you or a spectator shake the coins vigorously and then throw them on the table. The ones that are lying with their backs facing upwards are sorted out. Repeat this until only one coin remains. Of course, exactly the one you predicted! Whether as a "mental act" or just to "earn" a quick beer, you and your audience will have fun!
