fresh paper with long full perfs all aroundEXTREMELY FINE ORIGINAL-GUM EXAMPLE OF THE 1863 5-CENT BROWN. A REMARKABLE STAMP.
The 5c 1861-68 Issue was printed from plates with closely-spaced subjects that left little room for the large 12-gauge perforations. The Brown shade, No. 76, is scarce in original-gum condition and truly rare in this high grade.

Scott values, which are influenced by the quantity of poorly centered copies extant, are irrelevant in the current market for original-gum classics.

The number of 24c Blackish Violet stamps with original gum known to us can be counted on one hand. Notable examples are the Caspary/Lilly stamp and the Wunderlich/Zoellner copy, which realized $40,000 hammer in our 1998 auction.
