THREE CENTS, ROSE; THREE CENTS, BROWN; SIX CENTS, ROSE AND SIX CENTS, PURPLE.

In the Postmaster-General's report for 1864 it is stated that "during the last session of Congress a bill was passed for the relief of the contractor for furnishing the department with stamped envelopes and newspaper wrappers, under the provisions of which the existing contract expired on Sept. 11, 1864."

With the renewal of the former contract Nesbitt changed the dies of the two, three and six cents. The first we have already exhaustively treated. It is, of course, the two cents, black, "U. S. POST". All these dies remained in use until June 30th, 1870.

As a matter of history it may be noted here that the three cents printed in brown, likewise the six cents rose, both on official size, were issued in July, 1865. The dies have a portrait of Washington facing to the left in a plain oval. It is enclosed in a frame of colorless lines. Inscription above "UNITED STATES"; below, "THREE CENTS" or "SIX CENTS", in block capitals. Large numerals of value at each side.

None of the Nesbitt die varieties have given the writer so many anxious hours and have required such prolonged study as the three cents of 1864. Indeed, the final solution of the problem of classification of the various dies was only arrived at after more than two years continuous research. Like the famous balancing of the egg of Columbus, the problem, when solved, is extremely simple. Looking backward on the long series of failures, it seems strange that the chief characteristics have so long escaped the attention of cataloguers. The fact, however, is patent. Even as thorough and painstaking a student as the late Gilbert Harrison who, in 1895, chronicled, as he thought, all of the existing die varieties of the three cents has failed to observe the most important differences. Indeed, in the entire philatelic literature dealing with the Nesbitt dies of 1864 there is but one allusion to the feature which constitutes the surest means for the identification of the die varieties, and this is only a single sentence contained in the Historical Notes of Messrs. Tiffany, Bogert and Rechert. It reads:—

"It is worth mentioning, however, that while dies 9, 15 and 26 (the latter the die under consideration) all have the small bust of Washington, there are small differences in each which show them to be different engravings. * * In die 26 the front hair shows only five locks and the back hair only four lines."

We shall presently see that, like the three cents, red of 1853, (Die A) the diemakers have produced different groups of heads which, once known, are not only an absolute means of differentiating the varieties, but also protect the collector from acquiring a multitude of the same die.

Although, as stated above, the die of the three cents rose equals that of the three cents red in the use of various heads, it is, otherwise, quite dissimilar to the first issue, as will be seen presently.

As in the varieties of the two cent dies the horizontal and vertical dimensions of the three cents vary greatly. After careful research and taking the advice of experienced philatelists, it was decided to adopt only two sizes for classification: i.e.
