20 Riels Prehistoric Animals - Indricotherium

Indricotherium — now more commonly assigned to the genus Paraceratherium — was a hornless rhinoceros relative from the Oligocene, and among the largest land mammals known to have existed. Cambodia's early-1990s prehistoric animal series was issued during one of the most turbulent transitional periods in the country's modern history, coming just after the 1991 Paris Peace Accords and amid UN-administered preparations for the 1993 elections. These coins were produced for the international collector market rather than domestic circulation, a common revenue strategy for smaller nations in the post-Soviet era.
