... one dollar coin yet?

...ir should be purple! Purple is the colour of royalty--very dignified. Twenty-dollar bills are green! Five-dollar bills are blue! Fifty-dollar bills are orange!

One dollar coins are gold, two dollars coins are silver with a gold centre! Your turn for having your pockets weighted down with coins falling through the holes is coming to YOUR pants. The colour for paper bills will be the least of your problems! LOL

Please stop your government from adopting the metric system because you'll never know for the rest of your life how much a pound you're being charged for your beef, pork, chicken, turkey, and lamb.

The term "green" is on everyone's minds these days, whether it's getting more green as in making more money, or going green environmentally. The need for more green technology and practices is
definitive, as the impact on our environment from our appetites for fossil fuel machinery and methods of generation electricity have taken a toll. An effort does have to be made to repair our planet, but many consider the loss of amenities to be too great to surmount. However, there are ways of getting by: solar water heating devices, electric high speed trains getting installed for public transport, and so forth. If you start going a little more green, it's like giving a cash advance to the Earth.

One of my favorite bills of all time was the old Irish 5 Irish Pound note, the one with Scotus on the front and the doG from the Book of Kells on the back, it all its glory.

As far as colored bills go, the set used for the Euro is most acceptable, both size and color are used to distinguish denominations, particularly helpful for the visually impaired, there is no mistaking a small blue 5 from the larger bluish 20 or the intermediate sized rose colored 10. The yellow/orange/tan of an even larger 50 is unmistakable, even to the least observant. The notes for sterling follow the same scheme as well. Without size differences, an unsighted person could not tell a five from a fifty as it was; dead easy to rob the blind that way.

Adam Smith in "Wealth of Nations" observed the only real measure of value was based upon labour but could not determine with the resources he had available how to come to a basic value figure given the complexity of input necessary to produce economic labour (complicated by educational requirements, training and skill development, etc. that are required to produce work). Today there are models that take all such complexity into account and produce finely tuned models of complex systems, forest energy flow ecosystems, weather, aerodynamic effects, even the virtual explosion of an atomic weapon. Still this modeling capability has not been applied to Adam Smith's fundamental observation as to the foundation of economic value - labor. What would the world do with a value that remains constant, year after year, is not effected by speculation, not readily inflated by scarcity or depleted by abundance; what would a currency unit accomplish if it were based upon an hour of labour, what value could be trusted for the currency to carry.
Much work needs to be done to build an alternate to the present economic system before the present system collapses from systemic economic bankruptcy, time is running out.

P.S. S.P. when are you on the road again, I am missing your travelogues already.

except for the $5 bill with that big gaudy purple numeral on it.

I did inhale.
