Large Treasury Notes

United States treasury notes were issued for 1891 and 1890.  Collectors sometimes refer to them as coin notes.  The basic design of each denomination from the two years is the same.  The only difference will be the seal size and type (which is sometimes different).  The back of the notes will always be different.  1890 examples have a dark and richly engraved green back.  The 1891 treasury notes have a plain back that is mostly green and white.  In most circumstances, the 1890 notes will be more valuable than the 1891 notes.
