Interesting. I must say that I find Swiss coins are quite logically ordered with respect to size denominating value. The only thing that drives me nuts is 1/2 franc coin - why does it have to be so small and almost the same size as the 10 and 20? And they should drop the 5 from circulation as well - it's totally useless. Adding some graphical designs to the Swiss coins might have also made them a little more exciting..

They kind of went the opposite way with the 20 and the 50 as the Aussies did - I always found the Australian 20 and 50 cent coins ridiculously large!
