Scott C1–C6 – Mint Plate Blocks of Four – Early U.S. Airmail Classics (1918–1923)

This curated six-piece grouping offers mint plate blocks of four from the earliest years of U.S. airmail service, including the iconic C1, C2, and C3 “Jenny” issues and the beautifully engraved 1923 series (C4–C6). Plate blocks from this era are increasingly difficult to source in clean, well-margined condition, and a matched offering spanning 1918 through 1923 is a standout opportunity for any collector specializing in classic U.S. Back-of-Book material.

Each block features intense color, sharp impressions, and intact selvage with readable plate numbers—attributes that place these firmly into the premium category for early airmail holdings. The Curtiss Jenny designs remain among the most recognized images in philately, and plate blocks of these values have a long history of collector demand.

For aviation enthusiasts, classic-engraving collectors, and Back-of-Book specialists, this curated set offers exceptional display potential and serves as a significant cornerstone of early U.S. airmail history.
