An 1899 Straits Settlement 4c is valued at $22,269-29,693 ahead of an auction at Spink Singapore.
The lot is one of nine surviving "surcharge omitted" specimens to bear this date and denomination.
The surcharges were introduced due to shortages of stamps in the Straits throughout the 1800s.
The region comprised modern day Malaysia and Singapore.
It remained a British crown colony until 1946, barring a short occupation by the Japanese in 1942-1945.
The auction will take place on September 10.
We have an 1892 Straits Settlement 32c surcharge omitted stamp for sale.
