100 Đồng

Vietnam's doi moi economic reforms were formally announced in December 1986, but the monetary pressures that made them necessary were already acute by 1985. This note was issued the same year the government attempted a currency conversion — exchanging old dong for new at a rate of 10:1 — a measure intended to wipe out black-market holdings but which instead accelerated public distrust of the banking system. Inflation was running at several hundred percent annually by mid-decade.

P#98 belongs to the pre-reform series that was rapidly rendered obsolete and withdrawn, keeping surviving uncirculated examples rarer than the quantity printed would suggest.
