These fourth edition sample notes of North Korea have appeared in the market since the currency reform of North Korea in 2009. This is because North Korea's currency reform is a big news in the world, and many people's eyes are focused on North Korea's paper money. North Korea took the opportunity to print the fourth edition of Korean banknotes and the fourth edition of Korean banknotes samples and sold them to foreign money merchants (anyway, the fourth edition of Korean banknotes in the currency reform has been invalidated, and these printed fourth edition of Korean banknotes and the fourth edition of Korean banknotes samples can only be circulated as collectibles and will not affect the Korean domestic market), so a large number of fourth edition Korean banknotes and fourth edition Korean banknotes appeared in.
This kind of paper money sample ticket was printed by North Korea purely to earn foreign exchange, and its circulation is unclear (but it is definitely huge and may be printed at any time). Although it is collectible, it is of little value.
The truly collectible Korean banknotes are: the first edition of the original Korean banknotes (1947 original watermark) and the second edition of the Korean banknotes (1959 edition). You can pay attention.
