The Malaysian ringgit (plural: ringgit; currency code MYR; formerly the Malaysian dollar) is the currency of Malaysia. It is divided into 100 sen (cents). The ringgit is issued by the Bank Negara Malaysia.
Bank Negara Malaysia first issued Malaysian dollar banknotes in June 1967 in $1, $5, $10, $50 and $100 denominations. The $1000 denomination was first issued in 1968. Malaysian banknotes have always carried the image of Tuanku Abdul Rahman, the first Yang di-Pertuan Agong of Malaysia.
ATMs normally dispense RM50 notes, or more rarely, RM10 notes in combination with RM50 notes.
Malaysian banknotes have long followed a colour code originating from colonial times. In the lower denominations this pattern is followed by Singapore and Brunei, and when Bank Negara first introduced the RM2 note it copied the lilac colour from the Singapore $2 note.
