I am a frequent visitor to the Netherlands. Prior to the adoption of the Euro, I found that I had to take a little more care when handling the Dutch currency compared to the currency of other countries - their series was 5c, 10c, 25c, 1G, 2.5G with 5G, 10G, 25G and 50G notes.
In contrast, the Euro was well researched in terms of ergonomics - it has 1c, 2c, 5c, 10, 20c, 50c, €1 and €2 coins with €5, €10, €20, €50, €100, €200 and €500 notes. The 1c and 2c coins are very small and two countries (Netherlands and Finland) do not use them, otherwise the coins are well thought out - each has a different milling pattern. The notes are all different sizes, each 3mm higher and 6mm longer than it predecessor. There is however a question as to whether €200 and €500 notes are needed. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ziser, Jesse Sent: 26 April 2008 06:12 To: U.S. Metric Association Subject: [USMA:40800] Re: Unknown series --- Pat Naughtin <[EMAIL PROTECTED]> wrote: > On 2008/04/26, at 9:43 AM, Ziser, Jesse wrote: > > The Online Encyclopedia of Integer Sequences calls it the > > "Hyperinflation Sequence for Banknotes". > > http://www.research.att.com/~njas/sequences/A051109 > > > That is surely a fancy name for a relatively simple series.

I don't disagree with you. I can see how the U.S. system of denominations might not be the best. I wonder whether the fact that the US was one of the first countries to use decimal currency means we are likely to have a less refined system than others. Incidentally, the "50" in that sequence is very rare. I've only seen a few half-dollar coins in my life. The dollar coins were pretty rare too, until they were recently reintroduced in "golden" form. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
