Watch List notes:

British Guiana 1.10.1938 P-13b PMG Very Fine 25 2 DollarsA simply excellent note for the technical grade, mostly clean and rare. For this date, there are only a few known prefixes. Rare and quite desirable with such good visual appeal. PMG placed a comment for minor rust on the back of the holder, but it is barely noticeable compared to the excellent paper quality seen. PMG mentions "Minor Rust"
