If you were to de-face a £5 or £10 note...?

You would be locked up in the tower of London for the amusement of her maj and the delictation of American tourists. The money would be valueless, so if you have any please send them to me for suitable destruction.

No...and you'd probably go to jail for trying to rip off the U.S Mint.

Tell your bank to stop payment on the account...

I usually go answer Tech questions, but this was too much to resist :)\n\nThis to me, depends on the quality of the money, if I see a shiny penny, I would pick it up, though I wouldnt get close to it if it was covered with gum, mud, etc, all depends on condition. \n\nAs for anything larger than a penny, I honestly dont care about the condition unless it was really disgusting, cigarette ash, gum, poop, none of that stuff and i'll take it :)\n\nFor bills, my eye that looks for cleaniness goes blind and I dont care what condition it is in, its money! In fact, I once picked up a McDonalds coupon good for a Big Mac half off with purchase of a Big Mac. Since it says "No actual cash value", I guess I picked up things that are worthless as well :)

Take it to the bank.  The will accept it, as long as the serial numbers are legible and at least 50% of the surface area is legible.\n\n-Wes

I'm guessing that you mean a savings account book, what they write in it means nothing unfortunately, their computer system will only have credited you £10.\n\nThat said i'd wait a couple of months and go in and ask them to update the book with any interest thats due, play dumb and say you're not sure if you're due any but you're just curious. If the balance is £10,000 plus a bit of interest, withdraw it all immediately and blow it.

The more comfortably well off you are financially, the less you have to worry about paying off bills...... such as a big electric bill..... or perhaps your car suddenly needs the head gasket replacing, or the brakes overhauling...... and you don't have to worry as much about your bank screwing you with a £28 after being put overdrawn by a direct debit (or the bank fining you after they put you overdrawn by fining you).

write money enclosed on the outside.  and then glue it shut

I sure wouldn't do as others suggest by ignoreing the dated item.  When it bounces and it will, expect to be charged the fees by your bank.  Best contact the issuer and return for a new one.

Yes, any bank will do this when supported with the correct identification.  You may have to pay a surcharge however as you will be converting Sterling to Euros.

I always pick up any money I see lying around.  I don't little kids picking it up and washing it off in the mouth like I use to do.  LOL  I always had to see how shiny I could make it.  so, my answer is a penny.

I would "recall" all debts owed to the US.Inflation would be erased.

I would think everyone knows how to get it right, but explaining why the given calculation is wrong is what we are interested. \n\nThe key here is that £2 came from the £27.  So there is no  way you add £2 to the £27 again!

I doubt you would be able to use it in a shop, but a bank would change it. Go to the bank of England's web site and have a look.

Let's just say you aren't going to retire with it.  About 5 cents, 30 cents in mint condition.

None.  Use a debit card, save money, invest.
