Infographic Coins

Posted by definitive touch, December 8th, 2009


The evolution of pocket change has been long and coming. Finally, Japanese designer Mac Funamizu has taken the idea to a completely literal level, designing coins in the shape of their respective pie chart ratios. Instead of a full circle for a 25 cents piece, it is shaped in to a quarter circle, and half a dollar is exactly a half circle shaped coin.

    Sharp Edges?
    interesting but not pratical.
    wonder what would happen if you had these in your pocket and fell over

    Looks good.
    But My first take is that it might get tricky to stack when I’m handing some change to someone. The good thing about current mostly circular coins is that, though of different diameter, you can usually hold them all as a stack in one hand.

  3. Lone says:

    A good self study. This was done centuries ago, except the coin was minted whole with a mark in the center that guided cutting it into fractions as the need arose. Sharp metal corners are not very popular though.

  4. Allegra says:

    Good idea!
    One potential issue I foresee with the simplicity here: too easy to counterfeit.

    This would help the blind, I suppose… very small children, and enormously stupid people (although the nickel and penny aren’t intuitive.) The cost of re-engineering machines to take these coins would outweigh the benefits, IMO.

  6. BinaryPusher says:

    Yes! looks very cool. Although I recon the 1c,5c and 10c denomonation needs a bit of a rework … I like the concept of utilising a percentage of the primary but it’s disparate to the 25c and 50c visual percentage concept.

  7. Stephane says:

    Interestingly, “coin” is French for corner

  8. Kyle Steed says:

    So in essence what you’re proposing is a whole new market just for custom change purses. I like the creativity though, but not sure how practical it is. The only place I’ve been that still rely heavily on coins is Japan, and even their money is becoming more and more electronic.

    I don’t understand why the Quarter doesn’t accurately represent a quarter of the dollar. The half dollar is awesome, but then the quarter being larger than the half dollar just ruins it for me…

    Creative Commons, a design firm?

    There is no design firm here, but a design concept by Mac Funamizu, an in-house web/graphic/industrial designer working in Tokyo, Japan (see About section)

  11. Hatsharpener says:

    This is complete form over function. Looks cool, but that’s about it.

    Sharp corners are impractical, and the amount of redesign required for Coke machines, parking meters to and whatnot to recognize coins based on these attributes would be ridiculous.

    Not to mention that their hierarchy system is almost as inconsistent as modern coins.

    Coins themselves will likely be retired before anything like this happens. Coke machines and parking meters are already taking credit cards. Money as a physical object is being phased out, and this already has the feel of futuristic things designed in the 1960’s that completely missed the mark.

    Thanks Snop, for pointing out the error, we originally sourced the correct site, but gave credit to the wrong party, which we have since cleared up.

  13. Jonathan says:

    This isn’t really a new concept. The romans used to do this, as well as many other countries back before modern machinery was in place to produce money. Obviously, “quarter” came from a “quarter” of a whole – a circular flattened piece of gold or silver with indented hammer marks so it could easily be split up into pieces – up to eight.

  14. Joey says:

    Please, if you are trying to introduce a currency concept for a country that speaks English, get your grammar correct. Fifty CENTS. Plural. With an “s.” Sorry, that just drives me crazy.

  15. Gabriela says:

    Wow. really good concept and project. the idea could be used before in ancient civilizations, but it still looks innovative nowadays. If it would be necessary to re-engineer machines or something else, it doesn’t matter. this one is a good concept, anyways.

  16. Scott Falkner says:

    I, fir one, will be very reluctant to dig into a jar if pennies.

  17. ces says:

    it would be really cool if the coins had a grooves in which you could slide the coins into each other – to make a dollar coin. That would get rid of some of the sharp edges – but probably promote Obsessive Compulsive Disorder

    Kinda makes you wonder. You heard it first here. Good stuff. :)
