Gibraltar is a small British Overseas Territory located at the southern tip of the Iberian Peninsula, bordered to the north by Spain. Its currency is the Gibraltar Pound, which is locally interchangeable with the Pound Sterling, to which it is pegged at par; however, the Gibraltar Pound is legal tender only in Gibraltar and not in the United Kingdom.
The territory has also authorised some mints to issue commemorative and other non-circulating coins under its jurisdiction. Some of these are not in standard sizes; listed below are silver coins denominated as £1 (One Pound). |
