Centennial Covers cachet

This page contains (selected) covers with "Centennial Covers" cachets, mostly on un-manned satellite (or scientific rocket) launch covers. These covers from 1962 thru 1984, almost always without any logo (rare/exceptional items with a text logo are included in the list below), were produced by the late Edward Hacker of Huntsville AL. Centennial sold its remaining cover collection in 1984, but continued to produce covers for Space Shuttle events.

On this page, "selected" indicates covers for un-manned satellite (or scientific rocket) launches only, excluding manned missions for which additional covers exist but are not included.

Readers who know of additional information or images are invited to contact the authors using the e-mail addresses found at the link at the bottom of this page.

1Pioneer-5 and Explorer-6 were similar "paddlewheel" satellites. It is believed that Explorer-6 contained two short antennas on its "top", whereas Pioneer-5 contained only a single short antenna. When there are no antennas on top, the distinction is unclear, but of the two, Pioneer-5 is assumed.
