The local currency is Singapore dollars. It comes in notes and coins. Notes come in SGD 2, SGD 5, SGD 10, SGD 20, SGD 50, SGD 100, SGD 500, SGD 1,000, and SGD 10,000. As a matter of fact, I have yet to seen a SGD 10,000 bill. The main reason I can think of, is the wide usage of credit cards in Singapore. The most commonly used credit cards in Singapore will be Visa and MasterCard as compared to American Express, Diners Card or JCB.
