I've just picked up my dollars from the currency exchange before my visit to the US, and notice that there is a new style $20 bill (series 2004).
Being used to our Bank of England's habit here in the UK of changing our bank notes every few years and making the old ones no longer legal tender, are the older $20 bills that I still have from previous visits still in circulation?

Yes they are and not to worry, they are still legal tender.

Yes, and I bet with the current exchange rate you have a lot more dollars, yes? ;-) You are lucky, I am going to the UK in Feb and Sept, and my poor little dollar, won't buy nearly as much as it used to!

The "old" dollars will be retired as they circulate through the US Federal Reserve system. Not to worry. As stated, they are still good.

Good question, one that would never have occured to most people living in the US.

Old US money is good from any period, though as it gets older it is worth more as a collectable than as money.

Nice to see the number of questions about the US from folks in Europe increasing on this board. The weak dollar may help this year's US tourism.

Thanks for all the answers. I have just received $350 for £200.08 (at a rate of $1.75 to £1). When I visited NYC last summer, I got $1.38 to £1. It's now the same as someone just giving you $0.50 back ever time you spend $2. Sorry, but it will make it a heck of a lot cheaper.

These things come in cycles. Now it's Europe's advantage. In a few years, it will swing back to the dollar. Take it while you can get it and enjoy your trip!!!
