Fr. 127. 1869 $20 Legal Tender Note. PMG Very Fine 20. $20 Legal Tender notes from this popular Rainbow Series of 1869 are quite difficult to obtain in any grade, and become quite difficult to obtain above the Very Fine level. Light blue undertint is still detected at right, while faded red ink compromises the design at top, around the serial number and the treasury seal. The reverse of the note shows the "Legal Tender" clause at center, "20" counter at right and "XX" counter at left. PMG comments "Ink."
