Will there ever be a one world currency?  Or how about an end to currency?

Yes. In many ways it began with the advent of the euro. It is inevitable that the lines that divide nation states will blur as the centuries pass. Many, most, world economies today depend on other nations for economic support and trade, one of the first steps in global unification must be the integration and enforcement of a single world currency.\n\nThere will, and can, never be an end to currency. For as long as humans have existed there has been some kind of exchange for goods or services offered. Whether the bone necklaces and tools traded (used as currency) by our prehistoric ancestors or present day credit card transactions there is a need for some form of currency to obtain something in which one cannot make, whether through lack of skill or resources, for themselves. As long as humanity exists some form of currency must exist.

It's really a matter of the confidence of the people in our system.  Since our currency is fiat money, that means there's no gold or anything backing our money, it's only worth what people believe it to be worth.  As long as people have confidence in the system it will continue to work.  If people give up and lose faith in the system, it could theoretically collapse.  Personally I don't think it will.  That said, the advice you mentioned is good.  Those investments tend to be less affected by market forces.

Sure.  We have more important domestic and international matters to worry about than the traditional semantics on our currency.  Fix other things.

This is definitely an urban legend.\nIn fact, Canada does not currently have bank notes for either one or two dollar denominations.

NO\nit has never been an issue in the past, and the cost to do so would be astounding, let alone how does this judge propose getting all of the current currency out of circulation,WORLDWIDE??\nisnt our national debt high enough already???

It wouldn't work because it would require a mass undertaking that the government is not willing to do.  Making all current money obsolete and changing the "face" of currency is a huge ordeal.  Not only does it require the government to create the money, it would have implications all the way down the chain!

YES cuz just 3 months ago I was looking for the same thing! Go to http://www.tredthgjtotiugilaf.com and you will be able to find a faliguitotjghtdert of your own!! I enjoy mine every day and it was well worth the money. The only thing is they don't accept U.S. currency because it comes from the country of faliguitodert and they only accept tjghtderts as currency. But the exchange rates are hard to calculate so I suggest you go to http://www.tredthgjt.com and utilize their professional currency exchange services. I hope it serves you well! And as they say in that country, instead of good bye...dertfailguitotjgh!!

Currently the type of war{s} the USA is involved in can bankrupt the entire world.\nWhy?\nBecause the U.S. dollar is the worlds currency of choice, since the 1944 Bret-ton Woods New Hampshire agreement.\n\nIf and when other countries choose to use other types of money for international payments, the eventual ramifications could//would have severe consequences in the USA in the form of a depression. Many countries worldwide are apparently now opposing the U.S.perpetual war policies. \n\nAlso, since average American wages have lagged far behind the rising costs of home ownership or rental expenses it is exceedingly more difficult for the middle class American families to raise their standard of living.

NO!!! people complaun about the different currencies but inteligence just over idiot can keep it straught. i miss the different looks & textures. i still, after all this time, hear complaints from the richer countries that the euro has thrashed their wealth. the poorer countries complain about the prices of goods. i hope uk never adopts it, it would be disasterous for the britton. travel in eu isnt better but its not worse unless i intend on buying low & selling high.

Honestly? probably never again. World consumption far outpaces production (Thanks to China) coupled with production troubles (political and economic instability in producing countries) mean we will be paying higher prices. (Don't forget inflation too).

There would be two problems - getting readers that count the foreign currency, and getting up-to-date conversion rates sent to it, so that you con't get cheated by currency rates changing.\n\nYou'd have to set it up so that it either gets an update once per day, say, or like an ATM, it would 'phone home' for every transaction to verify rates.  A daily update would be more efficient.\n\nAnother problem would be displaying the prices.  You'd need a touch-screen with a menu system, first showing a menu of currencies accepted, and then the items for sale (so that you can display the menu in the currency of choice)  If the item menu displays the prices in several different currencies at once, it would be too cumbersome.\n\nHer's another option - say you are returning from Europe with a few Euros here, a few pounds there, some Rials, and a few Rands.  It would be cool to select an item and just start feeding in all those different currencies until the item is paid for, and it spits out change in Dollars or something.  This would make displaying prices difficult, since you are using several currencies to pay for an item, but this would be a valuable thing to have in airports around the world.\n\nInteresting idea.

no, this leads to hyperinflation and the currency becomes worthless. great examples can be found in former east germany, bolivia, etc.

Currency denominations on one country are not based on currency of another country. The US dollar is a standard of measure in the US, regardless of its performance against other currencies, such as the Euro or pound.
