500 Won Brontosaurus

North Korea's hard currency commemorative program expanded aggressively in the early 1990s as the regime sought foreign exchange through coin collectors abroad — pieces like this were never intended for domestic circulation and were sold almost exclusively through overseas dealers and trade channels. The brontosaurus subject places it within a broader series of nature-themed issues from Pyongyang that targeted the Western collector market during a period of acute economic contraction following the collapse of Soviet aid.

KM#62 is attributed across a three-year span, suggesting either phased releases or restrikes — a common and poorly documented practice with DPRK commemoratives of this period.
