The Die Varieties of the Nesbitt Series of United States Envelopes

A detailed handbook catalogs the die varieties of an early United States stamped-envelope series, describing each issue, individual dies, head types, and distinguishing features such as letter spacing and label shapes. Material is organized chronologically by issue (1853–1865) and supplemented with reference lists, an appendix, addenda, and errata. Precise technical descriptions analyze retouching and repairs, paper colors and textures, envelope sizes, and loop counts, often providing measurable traits to aid identification. Practical commentary addresses collecting challenges and offers classification guidance for cut squares and entires, with methods to recognize and record subtle varieties.
