A good thing about running your own country is that you can create your own currency (though it can be a bad thing, too - anyone remember the Japanese 銭? It was the version of the Japanese penny until postwar inflation made it worthless). The country of the Cook Islands has concocted a way to literally mint their own profits by issuing Kumamon-themed coins as legal currency. They come in two valuations: one gold and one silver. I doubt either will be accepted by vending machines as the former costs 39,800円 and the latter 19,800円, exclusive of tax. Still, they’re cute, and undoubtedly many Kumamon aficionados will buy them. - William
