50 Tyin

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 created tenge — was introduced in November 1993 alongside the tenge itself, replacing the ruble in a rapid, tightly controlled currency swap that gave citizens just three days to exchange their holdings.

The brass composition was a practical choice for a state that had just inherited Soviet-era minting capacity and needed to produce an entirely new coinage series quickly and cheaply.
