This is an 1851 obverse and reverse die trial described as struck on glazed board. We have assigned it number P3115. It was part of the Longacre materials given to the Library Company of Philadelphia by Maxwell Whiteman. It is accompanied by a March 24, 1851 letter from Longacre to the Secretary of the Treasury which says, in part: “It is the first impression I have taken from the dies I have been preparing for the three cent piece ordered by congress.” To your editor's knowledge, these have never before been published or seen by the collector fraternity.

It was accompanied by an original signed letter, dated August 17, 1857, of George F. Nesbitt who held the contract to supply imprinted postal stationery to the Post Office Department from 1853 until 1870. A new stationery design was evidently contemplated. The letter to Third Assistant Postmaster General reads in part: “I called at the United States Mint yesterday ... Mr. Longfield (sic. - James Barton Longacre) informed me that there was no Head of Washington at the Mint that he thought suitable for the purpose .... Mr. Longfield recommended the enclosed as a suitable mark for the three cent envelopes." This second example along with the letter now illustrated below are in the collection of Mike Byers. We would also like to thank Richard Frajola and Mike Byers for sharing this was us. Images of the second example and the Nesbitt letter are courtesy of Mike Byers.
