How to Identify the Abbasid Copper Fals

Start by confirming that the coin is entirely epigraphic. An Abbasid copper fals carries only linear Arabic script on both faces, with no portrait, animal, or figural device anywhere. The obverse of this type shows Arabic inscriptions accompanied by decorative elements, and the reverse carries further Arabic text that includes a mint designation. If you see any human or animal image or any Latin lettering, you are not looking at an Abbasid fals.

Read the legends to attribute the piece. The central inscriptions are religious formulas typical of Islamic coinage, while the reverse mint-and-date formula is the key to a specific attribution: it names the mint where the coin was struck and the year, both spelled out in Arabic words rather than numerals. On this coin the date is AH 219 (834–835 CE). Being able to read, or match against a reference, the mint name and the Hijri year is what separates one Abbasid fals from another.

Check the physical coin. This is a copper piece, so expect a reddish-brown to dark oxidized surface, sometimes with green corrosion products. Fulus are small, hand-struck coins that are often slightly irregular in outline and unevenly centered, with part of the legend running off the edge because the dies were larger than the flan. Copper is non-precious and will not have the bright tone of silver; weight and diameter vary from mint to mint since fulus were not held to a strict standard.

Watch for look-alikes and be cautious about attribution. Umayyad, later Abbasid, and various successor and provincial dynasties all struck superficially similar all-Arabic copper coins, so the specific mint and date legend — not the general appearance — is what pins a coin to AH 219 and to the Abbasid series. Worn or corroded fulus with illegible legends often cannot be attributed with confidence and should be described cautiously.

Apply sensible authentication checks. Genuine fulus are struck, showing the slightly uneven relief and flan shape of hand production; be wary of cast copies with soft, blurry detail, seams, or air bubbles, and of pieces with artificially applied "patina" hiding tooled or modern surfaces. When the legend cannot be read clearly, compare the coin against a specialist catalog of early Islamic copper coinage or seek an expert opinion before accepting a firm attribution.
