I won the red dot award: design concept 2013 and this time it’s ‘best of the best’ prize! The concept itself is the one I posted here a few years ago (below), but I revised it based on some positive feedback from the readers for more practical use. I really appreciate everyone who helped this to happen. Thanks!!
Infographic Coins are a set of coins whose values are easily recognized by anyone. By utilizing shapes of pie graphs, which are widely used around the world by a variety of ages of people, one can instantly figure out how much these infographic coins are worth. One more important aspect of this concept is that by making the empty space in a pie chart, it saves the usage of materials, which is environmentally friendly.
(Below from here is the original version before the revision.)
The round shaped coins must have a lot of benefits that other figures such as a triangle or a square don’t. Also, non-rounded coins may have many demerits. Aside from those, travelers and other people who are not accustomed to the currency would be able to easily remember how much each of these coins is (as long as she knows how to read pie charts).
