[6] After Western Xia was annexed by the Mongols, Tangut inscriptions appeared only on a single Yuan dynasty coin.
[10] Cash coins with Tangut inscriptions have been discovered in the modern era such as the Zhengde Baoqian type in the year 1999.
[11] During the Qianyou period (1139–1193) of the reign of Emperor Renzong the political and military stability as well as the growing economy in Western Xia had allowed for the country to prosper.
Emperor Renzong would hold education in a high esteem and was responsible for the establishment of schools including an Imperial Academy.
[8][9] During the Qianyou era the Tangut government had also gained greater respect for both Confucian philosophy and the culture of the Song dynasty.
[8][9] These cash coins were unearthed due to Helanshan flash floods which occurred near Yinchuan, which was historically known as Xingqing and was the capital city of the Western Xia Empire.
[8][9] Dr. Zhu Hu (朱浒) of the Art Research Institute of East China Normal University published in “Volume One of China Numismatics” (simplified Chinese: 中国钱币2016年1期; traditional Chinese: 中國錢幣 2016年1期; pinyin: zhōng guó qián bì èr qiān liù shí liù nián yì qī) an assessment of this cash coin.
[8] Another difference between these two cash coins is the fact that the "crown" of the seal script "Bao" (宝) character of the Guangding Yuanbao has a more "square" shape compared to the more "round" shape of the "Bao" found on the seal script version of the Qianyou Yuanbao.
[8] All of these differentiating characteristics are also found on the seal script "matched cash coins" produced by the Song dynasty.
