Reverse description	The large numeral '50' dominates the central field, with the denomination ТИЫН (Tiyn) inscribed beneath in Cyrillic script. The date 1993 is divided across the lower portion of the coin, with '19' to the left and '93' to the right. The mint mark ҚҰБ (National Bank of Kazakhstan) appears to the right of the numeral. The entire composition is framed by a geometric eight-pointed star border executed in a traditional Kazakh ornamental style, with stylised angular motifs at each cardinal point.

Additional information	Kazakhstan declared independence in December 1991, but the new republic continued using Soviet rubles for nearly two years while its monetary infrastructure was built from scratch. The tyin — subdivisions of the newly introduced tenge — were issued in November 1993 alongside the tenge itself, introduced on November 15th of that year. The entire Soviet-era ruble stock was withdrawn within four days, a deliberately compressed timeline designed to prevent capital flight and ruble dumping across the border from Russia. The KM#5a reference suggests a recognized die or alloy variant exists within this type.
