The Monetary Authority of Singapore, responding to a letter about the use and acceptance of 5-cent coins, said the coins remain in use in Singapore and will continue to be issued to meet demand. It pointed to continued retail use, including supermarkets pricing goods in 5-cent increments and charging 5 or 10 cents for plastic bags, and said it will monitor the coin’s longer-term relevance. MAS also clarified that under the Currency Act, merchants may choose not to accept certain coins for payment if they put up a written notice to inform customers. It said merchants may weigh factors such as the impact on customers, the value of the transaction and the cost of handling coins, while customers remain free to decide whether to patronize those businesses.
