Cancellations

The Batu Caves post office is situated in the kampung of the same name near the famous Batu Caves hill. The post office opened on 25 November 1906. During the Japanese occupation, the Post Office remained open, and a modified pre-war cancellation was used, with Japanese characters. Although the post office is still in operation today, the cancellations no longer bear the name Batu Caves, having been replaced with the Kuala Lumpur chop.

Gunung Rapat is a major limestone hill in the Kinta Valley, south of Ipoh. It is home to many cave temples. It is not known if the post office still exists.

Batu Kurau is an isolated limestone outcrop at Anak Kurau, which is near Batu Kurau in Perak. See Gua Kelawar and barber shop at Batu Kurau. Gunung Pondok is a large limestone hill at Padang Rengas, between Kuala Kangsar and Taiping in Perak.

Bank notes featuring karst features

On 8th November 2000 Malaysia introduced a new RM1 (one Ringgit) currency note - this is the lowest value of the paper money. On the back is a 'collage' of illustrations including a Malaysian kite, the beach, Mount Kinabalu and the pinnacles of Gunung Api in Mulu National Park.

Bank Negara Malaysia issued a new series of banknotes on 16 July 2012. Themed 'Distinctively Malaysia', the latest banknotes series draws its inspiration from the country's diverse culture, heritage and nature. The highest value note, RM100, features the pinnacles at Gunung Api, Mulu. They are next to Gunung Kinabalu in Sabah, and actually look as big as the Kinabalu mountain! Both these are World Heritage sites. See Bank Negara info and security features. See video. The pinnacles starts at 1.35 mins.
