HONG KONG. Mercantile Bank of India. $500, 26.5.1959. P-243s.Specimen printed by W&S. One of the highlights of the broad assortment of banknotes from Hong Kong we are offering with this high denomination large format specimen note enjoys tremendous color and detail throughout. Deeply watermarked paper is noticed along with a strong impression of the vibrant design. The paper body is strictly original throughout and it seems only a slightly irregular cut at the upper right corner prevented a Gem designation. Solid zero serial numbers and single signature at lower right with four small punch cancels and specimen overprints. A note that will be a highlight in any collection it enters.PMG Choice Uncirculated 64
