I.B.N.S. Journal V.22 No.2

(*) On September 22 1975 old South Vietnam notes of 100 Dong and higher denominations were exchanged for the notes of transitional series at the rate of 500 old Dong for 1 new. The coins and banknotes in lower denominations remained valid, but at the value fixed by the new rate. With the exchange completed, the official rate of the new currency was set at 1.51 Dong per US$, but its real value, as reflected in black market trades, was closer to 6.5 to the Dollar.
