The official currency of Egypt is the Egyptian pound, or “Geneh” in Arabic, and commonly abbreviated as LE.
One Egyptian pound is 100 piastres, or "irsh" in Arabic.
There are banknotes of 1, 5, 10, 20, 50, 100, and 200 LE and there are coins of 25 piastres, 50 piastres, and 1 pound.
It can sometimes be difficult to find change for large bills so it is always advisable to have change on hand for taxis and tips.
