All currency notes and coins issued by the Monetary Authority of Singapore since 1967 are still legal tender and can be used to pay for goods and services in Singapore.

Alternatively, you can redeem past series notes and coins over the counter at a commercial bank in Singapore where you have a bank account. You may also deposit past series coins at MAS' appointed Circulation Coins Operator and Manager (CCOM), Certis CISCO Secure Logistics Pte Ltd (CSL)  via their self-service coin deposit machines or over the counter.

The bank or CSL will verify the authenticity of your currency before crediting the value into your bank account.
