Although many notes claim the title of "first" note issued by the United States, this is unquestionably the real deal, the rare Series 1861 $10 Demand Note, estimated at $125.000 is the only serial number 1 with the handwritten "For The" known from any of the issuing locations and one of only three Friedberg 7a's known.

The sale includes several other rare auction appearances,  such as a $20 1906 Gold Certificate graded Fine 15 by PCGS, which is the only known Gold Certificate Large Size star invert to exist estimated at $50.000 and a $100 1882 Brown Back note from The Union NB of Chicago estimated at $120.000 which is one of a literal handful of $100 Brown Backs from any location to receive a grade of 66PPQ or EPQ from either of the two major grading services. A curiosity is the $20/$10 1974 Federal Reserve Note, an error specimen. The double denomination has always been held in high esteem by paper money collectors, estimated at $25.000 it is likely to generate intense bidder interest.

The auction's selection of Face Proofs is led by a crisp and sharp Hessler SCE12 1895-dated $5 Educational Face Proof, estimated at $15.000. In comparison an exceedingly rare proof of an original series $1.000 face charter #290 U.S. National Bank Note, old for $96.050 at a Stamps, Coins & Postcards Auction held earlier this year by Philip Weiss Auction it is one of only two examples known.
