Space Memorabilia
Space Memorabilia FAQ
Authenticating and collecting astronaut-signed memorabilia, mission photographs, and NASA artifacts. Focused on Mercury, Gemini, and Apollo era collectibles.
Was John Glenn the first person in space?
No. Yuri Gagarin was the first person in space on April 12, 1961. Alan Shepard was the first American in space (suborbital) on May 5, 1961. John Glenn was the first American to orbit Earth on February 20, 1962, aboard Friendship 7. Historical precision matters for collectibles — Glenn items are tied to the orbital milestone specifically, not the first-in-space milestone.
How many times did John Glenn fly in space?
John Glenn flew twice: Friendship 7 in 1962 (three orbits, 4h 55m) and STS-95 aboard Space Shuttle Discovery in 1998 (8 days, 21 hours), becoming the oldest person to fly in space at age 77. Both missions generate distinct collectible categories — Mercury-era items command a premium over STS-95 era items for most collectors.
Is John Glenn's signature more valuable now that he's passed?
Glenn’s death in December 2016 permanently closed the supply of new signatures. Authentic, authenticated Glenn items have risen roughly 15–35% since then depending on format. Double-signed John and Annie Glenn items carry a further 2x–3x premium over solo-signed pieces — Annie Glenn’s separate passing in 2020 further limited that supply.
Why are Mercury-era Glenn autographs more valuable than Senate-era?
Mercury-era Glenn items (1959–1964) combine historical significance, strong visual iconography (NASA imagery, Friendship 7 capsule photos), and relative scarcity. Senate-era items (1974–1999) are more common and lack the space-mission context that drives collector premiums. The closer an item’s documentation is to the actual mission, the higher the value floor.
Are inscribed autographs worth less?
Inscribed autographs typically trade at 20–30% below an uninscribed version of the same format because the inscription narrows the resale audience. Exceptions: inscriptions to notable recipients (other astronauts, NASA officials, mission personnel) can add 10–25% premium above a standard uninscribed piece.
What's the difference between JSA Basic and JSA Full LOA?
JSA Basic Certification includes a hologram on the item and a cert card verifiable online — appropriate for items under $500. JSA Full Letter of Authenticity includes a detailed forensic analysis letter and is required for insurance purposes, auction consignment, and estate documentation. For space memorabilia over $500, Gauntlet Gallery requires full LOA before listing.
