Fr. 375. 1891 $20 Treasury Note. PMG Choice Uncirculated 64.A lovely example of this one year only type with the redesigned open back. This note is one of a known trove of high grade examples but that supply was quickly absorbed by collectors. The portrait is of John Marshall, Chief Justice of the Supreme Court from 1801 to 1835. The note itself displays a cherry red seal and serial numbers with excellent inks both front and back. Always an impressive type note and their 1890 counterparts are several times more expensive in the same grade.
