EDM challenge # 121

it's strange. coins always existed in my country but only in the last few years they have gained some value again. our money always lost value so quickly that coins never had any value to even buy a candy. in the old days people could but lots of food or things just some coins, nowadays they don't have such a big value but you need them all the time to speak on public phones or even to ride a bus. the only way to ride a bus is to use coins into a machine next to the driver. no coins no ride. so we are always trying to get coins when we buy something to later have "for the bus".
