FINE. NO MORE THAN A DOZEN EXAMPLES OF FLOYD'S GREEN STAMP ARE KNOWN TO US, AND OF THESE ONLY FOUR ARE IN UNUSED CONDITION.
John R. Floyd advertised the start of his Penny Post in July 1860. In June 1861, after the outbreak of the Civil War, Floyd sold the firm to Charles W. Mappa, but continued to assist in managing the post for several months before leaving for war in January 1862. Mappa in turn sold out to Kimball & Waterman in May 1862, and the post continued at least until November 1862 and then closed.
The Brown and Blue stamps were the first issued, and the Blue continued to be issued from 1860 through 1862. The Green stamps are known used only in October and November 1862, thus they appear to be the last printing, probably by Kimball & Waterman before the post was closed. The Blue is the most common, and the Brown is extremely scarce. The Green is by far the rarest, with only two recorded covers, six or seven used stamps off cover, and three or four unused stamps (three with original gum) known to us.
FINE. ONE OF FIVE RECORDED EXAMPLES OF THE JEFFERSON MARKET POST OFFICE STAMP ON BLUE PAPER -- EACH USED ON COVER, OF WHICH TWO ARE TIED.
The Jefferson Market P.O. was not officially connected to the New York Post Office, but used the "Post Office" designation in its name, much like Swarts and other contemporaries. The post is believed to have been operated by Godfrey Schmidt, who was listed in the 1850-51 city directory as Godfrey Smith at 6 Greenwich Avenue (source: Elliott Perry). In addition to the stamps issued by the Jefferson Market P.O., a stampless cover was reported by Thomas C. Mazza in The Penny Post (Jan. 1995). The stampless folded letter is addressed to Sing Sing N.Y. and bears a clear strike of a large Eagle-type frame containing "Jefferson Market Post Office/BY G. SCHMIDT & CO." in two lines. It also has a red New York Jun. 30 datestamp, and the letter is year-dated 1850. This 88L2 cover is clearly postmarked Apr. 15 (1851), which establishes at least a ten-month existence for the post, corresponding to the city directory listing for Godfrey Schmidt (Smith).
Our records contain four examples of 88L1 (Pink paper), all uncancelled off cover, and five of 88L2 (Blue paper) used on separate covers. The stamps were not cancelled by the post, but in two cases they are coincidentally tied by a postal marking. The five 88L2 examples are listed in our Sale 908, lot 4920.
