The Gibraltar Five Pound coins are similar to the British Five Pound coins in that although they are legal tender, the Five Pound coin is not intended to be a circulating coin, but a collectible of a commemorative nature and many businesses are reluctant to accept them. Gibraltar currency is only legal tender in Gibraltar and most authorities advise changing your currency before you depart Gibraltar. If you want to sell your Five Pound coin, take it to a reputable coin dealer.
