50 000 Won Donpyo

North Korea's internal bond certificates — of which the "donpyo" series is a part — function as a forced savings instrument rather than conventional currency. Citizens and enterprises are periodically required to purchase these, with redemption terms set by the state and frequently deferred or dishonored. The 2022 date places this issue within a period of severe economic contraction compounded by extended border closures the DPRK imposed during the COVID-19 years, which effectively severed the informal Chinese trade networks that much of the population depended upon.

Whether these were redeemable in any practical sense remains genuinely unclear from available documentation.
