3c Scarlet (74). Unused
(no gum), bright and fresh, exceptionally choice centering with long full
perforationsEXTREMELY FINE. ONE OF THE FINEST EXAMPLES OF THE RARE 1861 3-CENT SCARLET TRIAL PRINTING WITHOUT PEN MARKS. THIS STAMP COMES FROM THE SCOTT GROUP.
The story of the 3c Scarlet has been well-documented by Jerome S. Wagshal in a series of articles appearing in the Chronicle (Nos. 56, 60, 61 and 62). Wagshal quotes statements made in 1893 and 1910 by a Washington D.C. stamp dealer, Carl F. Rothfuchs, to the effect that Rothfuchs obtained a supply of the 3c Scarlet in 1893 -- probably from the Post Office Department in exchange for his assistance with the Columbian Exposition -- and sold them with pen marks and original gum. The Rothfuchs lot is not from the same supply acquired by John W. Scott in the late 1870's, from which stamps exist uncancelled and cancelled with a New York City Station D oval. This unused stamp comes from the Scott supply.

5c Brown (76). Unused (no
gum), dark shade and proof-like impression framed by extraordinarily wide
even marginsEXTREMELY FINE GEM. THIS STAMP DISPLAYS MARGINS AND CENTERING RARELY ENCOUNTERED AMONG EXAMPLES OF THE 5-CENT 1861-63 ISSUE. TRULY OUTSTANDING QUALITY.
Although without gum, the centering and margins of this stamp are phenomenal. The 5c 1861-63 Issue (Buff, Red Brown and Brown) rarely come with wide even margins. This stamp looks more like its 1875 Re-Issue counterpart from the new wider-spaced plate. For the collector who is not concerned with original gum, this stamp ranks among the finest in existence.
