 As the language of the Kingdom of Kucha isn't well preserved in the modern era, many hypotheses have been suggested about its meaning, including that it is simply a translation of "Wu Zhu" or features the name of the Kingdom of Kucha in the Kuśiññe language.Cash coins without any inscription cast in this region (龜茲無文小銅錢, "qiūcí wú wén xiǎo tóng qián") are generally believed to have been produced between the years 265 and 589.The first variant of these cash coins are round in shape and have a rim around the square centre hole on one side (the other side is rimless).
