This gold dinar was minted between Hijri AH 690 and 694 (corresponding to AD 1291–1295) during the reign of Gaykhatu, the fifth ruler of the Ilkhanate.
The obverse of the coin is encircled by two concentric raised bands. Inside these bands, inscribed in two vertical lines from top to bottom, is the Islamic Shahada, a declaration of faith familiar to Muslims: “لا إله إلا الله” (Lā ilāha illa Allāh) and “محمد رسول الله” (Muḥammad rasūl Allāh), meaning “There is no god but Allah. Muhammad is the messenger of Allah.” Beneath this, the inscription “صلى الله عليه” (Ṣallā Allāhu ʿalayhi) is present, followed at the bottom by the smaller inscription “وسلم” (wa sallam), forming the common Islamic benediction “May Allah bless him and grant him peace.” Surrounding the outer raised band is an inscription, though partially illegible, it likely bears the official title of Gaykhatu, transcribed into Arabic as “أرينجن تورجي جاي خاتون بن أباقة” (Arinchen Turji Gay Khatu ibn Abaga), which corresponds to his Mongolian name, “亦憐真·朵兒只·海合都·伊本·阿八哈”.
The reverse side of the coin features an inscription in Uyghur-Mongolian script, written vertically from left to right: “ᠬᠠᠭᠠᠨᠨᠤ”, “ᠨᠡᠷᠡᠪᠡᠷ”, “ᠷᠢᠨᠴᠢᠨᠳᠤᠵᠢ”, “ᠤᠨᠳᠡᠯᠡᠲᠭᠦᠯᠦᠭᠰᠡᠨ” (Hagan nu Nereber Rinchindoji un deletgulug sen), which translates to “Minted in the name of the Khagan, Arinchen Dorji.” On the far right, there is an Arabic inscription “رينجن تورجي” (Rinchin Dorji), written horizontally from right to left after a 90-degree clockwise rotation. This corresponds to the phonetic transliteration of “亦憐真·朵兒只”, which itself is the Chinese transcription of the Tibetan name “རིན་ཆེན་རྡོ་རྗེ་” (Rinchen Dorje). This name, meaning “Precious Vajra,” was bestowed upon Gaykhatu by Kublai Khan. The influence of Tibetan Buddhism among Mongol rulers can be traced back to Kublai Khan, under whose reign Tibetan Buddhism gained prominence within the Mongol imperial court.
Gaykhatu was the younger brother of Arghun, the fourth ruler of the Ilkhanate, and the second son of Abaqa Khan. He was also the grandson of Hülegü, the founder of the Ilkhanate. Prior to his ascension, Gaykhatu governed the Anatolian Peninsula. In AD 1291, following the death of Arghun, Gaykhatu was elected as Ilkhan during a Quriltai assembly. During his reign, he continued military expansion into Anatolia while reaching a truce with the Golden Horde. In AD 1294, a severe rinderpest outbreak, combined with Gaykhatu’s excessive extravagance at court, led to a financial crisis. In response, he attempted to introduce paper currency, inspired by the Song and Yuan dynasties, and enforced its circulation by decree. However, the merchants and common people rejected the use of paper money, leading to riots in the marketplaces of Tabriz. Consequently, the currency experiment was abandoned. In AD 1295, a Mongol aristocratic coup overthrew Gaykhatu, replacing him with his cousin Baydu as Ilkhan. Gaykhatu was condemned by Muslim historians as a ruler indulging in hedonism, debauchery, and incompetence. However, his reign was marked by a policy of secularism and religious tolerance, extending protection to various faith communities, including Nestorian Christianity.
The Ilkhanate was established in AD 1264 when Kublai Khan ascended as Great Khan of the Mongol Empire and formally granted Hülegü the title of Ilkhan, ruling over a fief that became known as the Ilkhanate. In its early period, the Ilkhanate adhered to Mongol traditions and governance, following ancestral laws such as the Great Yassa and political institutions like the Quriltai assembly. Succession often followed the brother-to-brother inheritance model. However, after Hülegü’s reign, the administration increasingly adopted Persian bureaucratic systems, employing Persian aristocrats to manage financial affairs. Geopolitically, the Ilkhans initially maintained an amicable stance toward Christianity, seeking alliances against the Mamluk Sultanate and the Golden Horde. However, the local population and ruling elites remained predominantly Muslim. In AD 1295, after defeating Baydu in a civil war, Ghazan Khan ascended the throne and initiated the full-scale Islamisation of the Ilkhanate, marking a decisive shift in the state’s religious and cultural identity.
金幣正面有兩道同心圓凸紋環繞,凸紋內側由上而至下二行,為穆斯林熟悉的清真言禱詞「لا إله إلا الله」(Lā ilāha illa),「محمد رسول الله」(Allāh Muḥammad rasūl Allāh),即「萬物非主,唯有真主。穆罕默德,是主使者」。其下「صلى الله عليه」(Sallā Allāhu ʿalayhi),及最下方小字「وسلم」(wa sallam),為穆斯林常用祝禱語「願安拉祝福,並賜予平安」。凸紋外圈環繞有文字,辨識不清,但可能為海合都伊兒汗之正式名稱「亦憐真·朵兒只·海合都·伊本·阿八哈」,阿拉伯文轉寫為「أرينجن تورجي جاي خاتون بن أباقة 」(Arinchen Turji Gay Khatu ibn Abaga )。
金幣背面為回鶻式蒙古文,由左至右直式書寫「ᠬᠠᠭᠠᠨᠨᠤ 」,「ᠨᠡᠷᠡᠪᠡᠷ」,「ᠷᠢᠨᠴᠢᠨᠳᠤᠵᠢ」,「ᠤᠨᠳᠡᠯᠡᠲᠭᠦᠯᠦᠭᠰᠡᠨ」(Hagan nu Nereber Rinchindoji un deletgulug sen),意為「奉可汗亦憐真·朵兒只之名所鑄造」。最右側為阿拉伯文「رينجن تورجي」,為順時針旋轉90度後,由右至左橫式書寫,為「亦憐真·朵兒只」的音譯。亦憐真·朵兒只為藏文「རིན་ཆེན་རྡོ་རྗེ་」(rin chen rdo rje)之漢文音譯,為忽必烈所賜名,涵義約為「金剛寶鑽」,藏傳佛教風行蒙古君主亦由忽必烈始。
