where can i change my Brazil money which is the came out in 1988?i need urgent.. want to change it to pounds?

Answer 1

I'm afraid you're out of luck. All Brazil banknotes issued before the current Real - denominated notes issued in 1994 have been demonetized and are no longer redeemable.
The link below is to the Current banknotes page of the Banco Central do Brasil web site and has photos of all current banknotes.

Answer 2

Try your closest international airport. Banks will change currency as well but their rates are usually not that great. I am unfamiliar with Brazil's change of currency. I certainly hope that the money still has value.
