100 Tenge ARQAR

The Arqar — Siberian ibex — is one of several native fauna subjects in Kazakhstan's ongoing "Red Book" circulation bimetallic series, which draws from the country's official list of endangered and protected species. The series has been running in various formats since the early 2000s, with each release timed loosely to conservation awareness cycles rather than fixed annual schedules.

Kazakhstan's Red Book was first formally codified in 1978 under Soviet authority, then substantially revised after independence to reflect the country's own ecological priorities.
