Cairo is located on the banks and islands of the Nile River in the north of Egypt, immediately south of the point where the river leaves its desert-bound valley and breaks into two branches into the low-lying Nile Delta region. Cairo is the capital and largest city of Egypt and on the African continent. It is the Arab World's largest and Africa's second most populous city. While Al-Qahirah is the official name of the city, in Egyptian Arabic it is called by the dialect's name for the country, transliteration: Masr. Cairo was founded by the Fatimid caliphs as a royal enclosure. It replaced Fustat as the seat of the government. It later came under the Mamluks, was ruled by the Ottomans 1517 to 1798, and briefly occupied by Napoleon. Muhammad Ali of Egypt made Cairo the capital of his independent empire from 1805 to 1882, after which the British took control of it until Egypt attained independence in 1922. Cairo has a population of about 6.8 million people, according to the 2006 population census. The number of inhabitants was about a million higher at the time of the census, but this was adjusted downwards on the 17th of April 2008 when the new governorate of Helwan was created from parts of a.o. Cairo governorate. Cairo's metropolitan area has a population of about 17.8 million people. Cairo is the sixteenth most populous metropolitan area in the world. It is also the most populous metropolitan area in Africa.

American Silver Eagle

The American Silver Eagle is the official silver bullion coin of the United States of America. The United States Mint first released it in November 1986. It struck only in the one-troy ounce size, which has a face value of 1 dollar and guaranteed to contain one troy ounce of 99.9% pure silver. The United States Mint certifies its content, purity, and weight. Silver Eagle bullion coins, along with American Gold Eagle bullion coins are viable investment alternatives to the gold and silver bullion coins produced by other countries. To ensure wide distribution of the coins, the United States Mint awarded a contract to Grey Advertising to assist in marketing and publicizing the coins domestically and internationally. The design on the coin's obverse taken from the "Walking Liberty" design by Adolph A. Weinman, which originally had been used on the Walking Liberty Half Dollar coin of the United States from 1916 to 1947. As this iconic design had been a public favorite—and indeed one of the most beloved designs of any United States coinage of modern times, silver or otherwise—it revived for the Silver Eagle decades later. The obverse inscribed with the year of minting or issuance, the word LIBERTY, and the phrase IN GOD WE TRUST. The reverse is by John Mercanti and portrays a heraldic eagle behind a shield; the eagle grasps an olive branch in its right talon and arrows in its left talon, echoing the Great Seal of the United States; above the eagle are thirteen five-pointed stars representing the Thirteen Colonies. The reverse inscribed with the phrases UNITED STATES OF AMERICA, 1 OZ. FINE SILVER ONE DOLLAR, and E PLURIBUS UNUM as well as the applicable mintmark. Like the American Gold Eagle and American Platinum Eagle bullion coins, the United States Mint does not sell Silver Eagle bullion coins directly to the public. In order to provide "effective and efficient distribution, which maximizes the availability of the coins in retail markets as well as major investment markets" the Mint utilizes a network of authorized purchasers to distribute the coins. The coins sold in bulk at a premium over the spot price of silver. The coins sold to banks, brokerage companies, coin dealers, precious metal firms, and wholesalers that meet the following requirements. Be an experienced and established market maker in silver bullion coins. Provide a liquid two-way market for the coins. Be audited annually by an internationally accepted accounting firm. Have an established broad base of retail customers to which to distribute the coins. Have a tangible net worth of $5 million. Authorized purchasers must order a minimum of 25,000 coins, which they sell to secondary retailers that sell them, in turn, to the public.
