This is the rarest modern Malaysian RM100 that one could find. It was printed by Harrison and Sons. An earlier print with same design was by Thomas De LaRue, taking the prefixes from AG to AM.
The reason behind its rarity is that there are only 2 prefixes printed by Harrison and Sons....Namely AN and AP. This means that only 20 million pieces were printed at most.
After AP prefix, a new design, the WAWASAN series were released. This completely limited the number of these banknotes being circulated in the market.
The catalog price for this note is RM220, which i think is seriously undervalued...if anyone happens to come across a high grade such as UNC, AUNC, or even GEF...my recommendation...grab it...the chance of having a great piece of collection like this may never come again...
