    Description

    Natick Test Paper Overprint on Back Error Fr. 1910-E $1 1977A Federal Reserve Notes. Three Consecutive Examples. PMG Choice Uncirculated 64.
    We have in this lot a rare combination where error notes were printed on test paper. The third printing is on the back rather than in its proper position on the face of this third party graded trio. What makes these error notes truly special is the fact that they were printed on a special experimental paper that was designed to test the durability of various paper formulae. The government contractor for this paper was Natick Labs of Natick, Massachusetts. These Natick test paper notes can be identified by their serial number range of E76000001H through E80640000H, although research by small size specialist Robert Azpiazu and others indicates that large gaps exist in the numbering sequence. This tells us that the actual number of Natick test notes printed is less than the serial number range would suggest. Among examples in this lot, we see that the third printing on the back of each error note is dark. Also, this is the largest multiple of this error on Natick test paper to participate in our auctions. (Total: 3 notes)
