Whenever I travel to foreign countries, I not only try to learn their language and customs, but I also try to understand how their coinage works. Mac Funamizu has developed a solution for that. He has combined the art of the infographic with the practical use of coinage. All a consumer needs to know is how to read a pie chart. Another advantage of the coins is that it would be easy for visually handicapped persons to recognize the correct change just by the shape and feel of the coin, especially if Braille were added.

Sure, there are some drawbacks to non-round coinage. For one, the edges would wear down fairly quickly. For another, all the vending machines would need to be retrofitted to accept the new coins. A few simple changes to his design could yeild round coins for the 25 cent and 50 cent pieces to make it work, while keeping his elegance.
