SARAWAK. Government of Sarawak. $10, 1.1.1940. P-24.(KNB31) This bright $10 note is the finest we have handled for the denomination and is typically found in very low states of preservation. Bold red inks are located throughout and strong overprinting remains. A quick look at the PMG population report shows no pieces in the Uncirculated grade range regardless of date with only a single slightly more pleasing AU note better than the present piece. A small amount of a foreign substance is noted at the upper right margin which is mentioned by PMG in the comments section of the holder. Certain to be met with strong bidding by collectors.PMG About Uncirculated 50 Net. Foreign Substance.
