( the 1st banknote designation issued by Bank Negara). Can you imagine how great the value of 1000 ringgit at the time 1967? enough for wedding budget? tripping? or even buy a bungalow?

Specimen note issuing is extremely rare phenomenon in Malaysia Banknote History, it only issues in a very small quantity, thus it is high value for collection.
