1922 1c to 50c Set Overprinted "MALAYA-BORNEO EXHIBITION 1922", with May 25, 1922 postmarks. The complete set plus two varieties duplicated, all affixed to a sheet of paper before receiving SANDAKAN datestamps. The first 2c shows the "no hyphen" variety, listed by SG with a 50% premium for mint but used is obviously scarce and unlisted, so applying 8x for used suggests a top price of £880. The first 12sc has an unlisted variety of a broken last A in MALAYA, and finally the 4c has the variety of stop after EXHIBITION (this has a £200 premium in SG). Scott catalogue value is for 16 regular stamps, see close-up scans of the varieties online. An important exhibition item for the specialist. Rsv. $700. (Image)
