Instructions
View images of Arabic coins to become familiar with the size and inscription of the coins. Examples can be seen on websites such as World Coin Gallery.com and Worldwide-Numismatics.com. (See Resources)
Purchase or borrow a copy of a coin catalog that lists coins from around the world and provides examples and statistics about the coinage. One example is the Krause series of World Coin Catalogues, which contains in-depth identification and information about Arabic silver coins.
Find a conversion chart that will translate numerals in Eastern languages, making identifying an Arabic silver coin easier. Conversion charts are available in most coin catalogs and at websites such as WePlan.com. (See Resources)
Look for the image of a Toughra on the coin. The Toughra was a monogram of the current ruler's name and title at the time. Examples can be viewed at ChiefaCoins.com.
Look for coins that are between 17 mm and 37 mm in size. These are common characteristics of early Arabic coins. Most have Arabic written on the coin, and some coins will have a circle in the middle with four sections surrounding the circle, all with elaborate designs.
