Fr. 18. 1869 $1 Legal Tender Note. PMG Choice Uncirculated 63 EPQ.These "Rainbow," notes of the 1869 series are often graded by collectors and dealers with an additional caveat, color. This note gets high marks in that regard with deep blue tinted paper at left of center, dark green under-prints and a bold treasury seal. Original paper is easily identified and just a tight lower right is likely the only limiting factor in grade.
