Please, answer ! Monetary Value of Gibraltar Pound VS English Pound?

There is no difference

They have equal value

There is a difference, they are a different colour and you cant spend them in England.  The Gibraltarian Pound coin is also not accepted on aeroplanes as most of the them have been made in back street garages and are a slightly different weight.   However, a pound is a pound, Gib is a British Territory and if you are colour blind they do print the value on the notes so the colour differences is just a point of interest as there is no real difference and you can even change them in a UK bank when you go home.

Thats funny Back Street garages..

Thanks,  everybody  !     May  I  use  the  British  pounds  in  Gibraltar  or  must  I  exchange  the  British  money  to  the  Gibraltarian   pounds ?
