How to Identify the Ilkhanid Dirham

Begin with the layout, which is the most immediate clue. An Ilkhanid dirham is entirely epigraphic, and this type frames the obverse inscriptions inside an ornamental quatrefoil (four-lobed) cartouche, while the reverse arranges its legends in concentric bands enclosed by a decorative border. Small stars, dots, and floral ornaments often fill the fields around the panels. If you see a portrait, an animal, or Latin lettering, the coin is not an Ilkhanid dirham.

Read the legends to attribute the piece. The inscriptions combine religious formulas with the name of the reigning Ilkhan or overlord, and a mint-and-date formula naming the place of striking and the Hijri (AH) year in written Arabic words rather than numerals. Because the Ilkhanate spanned many mints and rulers and went through coinage reforms, matching the ruler's name, the mint, and the date against a specialist reference is what separates one issue from another.

Check the physical coin. This is a silver dirham, so expect a pale grey metallic tone, sometimes with darker toning, and a thin, hand-struck flan that may be slightly irregular or off-center. Weight and diameter vary across the series because different reigns and reforms used different standards; pre- and post-reform coins of Ghazan Khan, for example, differ in size and legend arrangement. Silver will not show the reddish-brown color of copper fulus.

Watch for look-alikes. Many medieval Islamic dynasties struck all-calligraphic silver dirhams, and neighboring or successor states in Iran, Anatolia, and the Caucasus produced superficially similar coins. Ornamental cartouches and concentric legends are characteristic of Ilkhanid work, but the specific ruler's name, mint, and Hijri date — not general appearance — are what confirm an Ilkhanid attribution. Worn coins with illegible legends often cannot be attributed with confidence.

Apply sensible authentication checks. Genuine dirhams are struck, showing the uneven relief and hammered flan of hand production; be wary of cast copies with soft, blurry detail, seams, or bubbles, and of pieces with tooled surfaces or added "toning" hiding modern work. When the legend cannot be read clearly, compare the coin against a catalog of Ilkhanid coinage or seek an expert opinion before accepting a firm attribution.
