Money coupons manufactured by North Korea’s Central Bank are proliferating throughout the country, NK News has independently confirmed, as the DPRK’s COVID-19 pandemic controls reportedly cause cash printing problems.

An informed source told NK News that the coupons — which photos show come in a 5,000-won denomination, printed with red ink on white paper — have been pumped out due to a shortage of North Korean won bills, confirming past reports on the presence of these coupons on the streets of Pyongyang. Asia Press reported that the coupons began circulating around the end of August.
