Analysis of 2 rupee coin

The new 2 rupee coin glistened under the KFC lights and as I took a closer look at its over simplified imagery and smooth form it looked unlike any other Indian coin I ever saw. To test its unique design would be great fun.

And so it begins, the experiment to know how usable the new design was.
Me: So here's a bag that contains different coins and kindly pick up a 1 rupee coin in 5 sec.
Subject A: (Moving hands in the bag) Here it is.
Me: Thanks, who is next?

After testing with half a dozen subjects, the results showed that 1 rupee coin was taken out successfully only half of the time and the in the rest of the cases it was the brand new 2 rupee coin that took its place.

A similar experiment followed with a 5 rupee coin with 100% success rate.

As we analysed why it happened,
We realized that the subjects while hunting for the 1 rupee coin, felt for smooth texture, lighter weight and limited thickness.

The premise for conducting such an experiment was to enact the real life example of taking coin out in a jiffy say while paying back to the auto fellow who is dying to leave, a crowded supermarket where people behind you are waiting in the queue, in a bus where you cannot let go of the handle bars for too long to pay the money for the ticket, etc. Coins are always given in a hurry also pertaining to its low currency value. So then fundamental charcteristics of shape, texture, weight and volume come into play very significantly.

So we placed a 1 rupee, the new 2 rupee and old 2 rupee coins on my palm with their backs upside and asked people around to tell me the currency on each one of them. They all gave correct answers for the 1 rupee and the old 2 rupee coin and but but not for the new 2 rupee coin. Besides the reason that it was new and wasn't very familiar to people, the new 2 rupee coin was hardly distinguishable from the 1 rupee coin. Also how is a visually impaired person supposed to make it out from the old 1 rupee coin? How are the millions of illiterate people we have in our country supposed to make it out from the old 1 rupee coin ?

So what goes in while designing a good coin?
Very fundamental things like size, shape, color, texture, weight, etc. All the factors that identify it in less that a second. Things where people don't have to read the text on the coin. Something that is accessible to everyone.

So let's start making life simple starting with the small things in life.
