several unofficial popular names are used to refer to different values of egyptian currency. these include (from the word "nickel") "nekla" () for 2 milliemes, "ta'rifa" () for 5 milliemes, "shelen" () (i.e. a shilling) for 5 piastres, "bariza" () for 10 piastres, and "reyal" (ريال) (""real"") for 20 piastres. since the piastre and millieme are no longer legal tender, the smallest denomination currently minted being the 25-piastre coin (functioning as one-quarter of one pound), these terms have mostly fallen into disuse and survive as curios. a few have survived to refer to pounds: "bariza" now refers to a ten-pound note and "reyal" can be used in reference to a 20-pound note.
