The current Orchids National Definitive 60 sen denomination, saw what is believed to be the final 2018 imprint coming out around early February 2019 with the prefix 2018/4. It was first reported sold in Johor Bahru.
Subsequently the 2019/1 prefix was first reported seen in the Kuala Lumpur General Post Office on 15 February 2019. However, the sheets were already sold out to a corporation.
