I recently purchased a 50 Dinar which is from Iran. Does anyone have any links? It has a lion holding a sword on the front.
The Persian sword-wielding lion was a common element of pre-Republic coins. It appeared on the following 20th Century 50 Dinar coins (I haven't checked the 19th Century or earlier, but I'm sure there are examples): KM#961, cu-ni, AH1318-37 (1900-18) KM#1091, cu-ni, SH1305-07 (1926-28) KM#1142, Al-bronze, SH1315-32 (1936-53) KM#1142a, copper, SH1322 (1943) KM#1156, Al-bronze, SH1332-54 (1953-75) KM11156a, Brass-coated steel dated MS2535-58 (1976-79) (Iran used several variant forms of the Muslim calendar before the establishment of the Islamic Republic of Irans.) Post a photo and we can precisely date it, and give you an estimate of value.
I looked, but I couldn't find a website that would translate the date. Is there anyway you can post a picture? I know someone will be able to help if you do.
What looks like "1777" would be 1666 in Arabic, indicating the Muslim date AH1666 which will be somewhere in the vicintiy of 2250 on the western calendar. On the other hand, if the "7" characters appear to be backwards it could be AH 1222 (March, 1807-February, 1808 - with a short top stroke), AH1333 (March, 1905-February 1906 - with a long, wiggly top stroke), or SH1333 (1954). Krause does not list any 50 dinar coins for AH1222, so, if they are reverse "7s" you probably have either KM#961 or KM31156, described in my earlier post. So, does the coin appear to be cu-ni or al-bronze
Cu-ni is copper nickle, the primary component of modern US coinage. Aluminum-bronze is usually a little more yellow than regular bronze, but it can age to a darker shade, and it is somewhat lighter than a normal bronze coin. All things considered, your coin is most likely the 18mm KM#156, of which more than 4-million were minted in SH1333 (1954). The 2006 33rd Ed. Krause values them from 75 cents (F) to $8 (Unc).
The information I have posted is all from the Standard Catalog of World Coins, 20th/21st Century, 33rd Ed. (2006), which is a metropolitan area phone book-sized volume, undoubtedly available in your local public library. This website mentions your coin, but doesn't have a picture up.
