Residents can turn unwanted local coins into notes or Octopus credit at the government coin truck that is visiting Tung Chung this week.
The free service, run by the Hong Kong Monetary Authority, collects excess Hong Kong currency coins and re-circulates them to meet demand.
The coin cart will be outside the Tung Chung Health Centre at Fu Tung Estate between 10am-7pm. The free service operates every day until Sunday (except Wednesday). It will return on October 23-29.
The HKMA has collected HK$354 million in coins since 2014.
