Nyasaland was a British protectorate, established in 1907 when the former British Central Africa Protectorate changed its name. Since 1964, it has been known as Malawi.

Below is the only association I found online between Nyassaland Coffee co and Ceylon.
George Mortimer Crabbe, was a veteran planter and sportsman. Mr. Crabbe was born at Elkaduwa, Matale. He was educated in England, privately and at Dawlish, South Devon. He came to Ceylon in 1887, after being engaged for two years in farming in New Zealand. He started coffee and tea planting under the late Mr. Thomas Mackie on Great Western, Talawakelle, and opened up El Teb, Passara, belonging to Capt. Gordon. In 1895, Mr. Crabbe went to Malangi in Nyasaland as Manager of the Nyasaland Coffee Company, but returned to Ceylon two years later and assumed charge of Marawela Estate, Ratnapura, with which he was connected until his retirement about eight years ago. Since then Mr. Crabbe resided on his own property, Arcadia, Diyatalawa, and did some visiting work. He Died in 1931 Sept 14th.

It is much larger than all Coffee tokens.
From size, and rarity. IMHO it may be just a uniface medal for display made by the company. Since lead filled was it a Paper weight.
