Fr. 28a. 1880 $1 Legal Tender Note. PCGS Very Fine 35 PPQ.A new variety has recently been discovered on the 1880 $1 Legal Tender note bearing the Scofield-Gilfillan signature combination. The variety is the engraved "Series of 1880" which is located in the top back margin. This engraved date is only on very early issued Fr. 1880 $1s and is not seen on the Fr. 29 through 33 1880 $1 Legal Tender Notes. PCGS has only graded two examples in all grades and this is the first example to be auction with this newly designated Fr. number. The new cataloging number is confirmed and will be added in the next addition of <em>Paper Money of the United States </em>21st edition that should be out early in 2018. Our estimate is purely a guess and we would not be surprised if it is surpassed.
