Just a clarification on the nomenclature: this is a "medal", not a "coin" or "token".
Cricket is not a popular sport in Singapore, despite the strong British colonial influence there. Singapore, as a heavily developed island city-state, just doesn't have the wide open spaces you need for cricket fields.
A relatively obscure sporting-memorabilia medal from an obscure sport in (what is for you) a foreign country, is not going to have much value, unless for some reason they actually made this medal out of solid gold. Gold was pricey in the early 1980s, so I would assume it isn't. Though you could always get it tested, to be sure.
Here's a kind-of-similar medal from the same club, from 1984, listed on a Singaporean
ebay clone for Sing$25 (about US$18):
