Here's a section that will really be of interest to Islamic-coins.It is about the Haj Pilgrim banknotes that were used in Saudi Arabia by Muslim pilgrims from other countries undertaking the Haj.I have 3 of the Pakistani Haj Pilgrim notes,but the Indian Haj Pilgrim notes are very difficult to find.According to an Indian banknote catalogue,the Indian Haj Pilgrim notes were printed not only as a form of currency control,but because there was supposedly an agreement to change the Indian Haj Pilgrim notes into Saudi Arabian Riyals when the pilgrims got to Mecca & Medina.
