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. Historical precision matters for collecting — Gauntlet Gallery documents astronaut-specific historical context on all space memorabilia COAs.

How many times did 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. Gauntlet Gallery carries authenticated Glenn signatures from both eras, certified by Zarelli Space Authentication.

Is his signature valuable because he died?

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, and double-signed John and Annie Glenn items carry a further 2x–3x premium due to Annie Glenn's rarity. Gauntlet Gallery authenticates Glenn signatures through Zarelli Space Authentication and JSA.

What's the difference between JSA Basic and JSA Full LOA?

JSA Basic Certification includes a hologram on the item and a certification card verifiable online — appropriate for items under $500. JSA Full Letter of Authenticity includes a detailed forensic analysis letter and is required for insurance, auction submission, or items over $500. Gauntlet Gallery requires full JSA or equivalent LOA on all space memorabilia before listing.

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 exist: inscriptions to notable recipients (other astronauts, NASA officials) can add 10–25% over standard. Gauntlet Gallery notes all inscriptions explicitly in listings and prices accordingly.

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), and relative scarcity. Senate-era items (1974–1999) are more common and lack the space-mission context. Gauntlet Gallery authenticates and prices Glenn memorabilia with era-specific documentation through Zarelli Space Authentication.
