Well that's cool. A square coin. Your coin is from the Straits Settlements, now known as West Malaysia, with its major city Singapore, on the Malay Peninsula of Asia. The name was changed to Malaya in 1939.

Great Britain issued coinage for the Straits starting in 1845 and continuing until 1935. The only square issues are the 1/2 and 1 cent coins of King George V. Here is what the catalogs say about them:

1/2 CENT
worn: $1 US dollars catalog value
average circulated: $2
well preserved: $5
fully uncirculated: $20

1 CENT
worn: $2 US dollars catalog value
average circulated: $3
well preserved: $6
fully uncirculated: $28

All dates carry roughly the same value. Our figures above are inflated catalog values. You can learn how to convert from catalog values to actual values at our Important Terminology page (link at upper left).
