Question 1

What is the most expensive space memorabilia ever sold?

Accepted Answer

Based on Gauntlet Gallery's database of 7,991 space memorabilia transactions, the highest recorded median price is $18,750 for Apollo 11 Crew-Signed Type Three Insurance Covers. Apollo 11 VIP Launch Invitations signed by Armstrong, Aldrin, and Collins have a median of $15,000. Mission-flown items command extraordinary premiums above these figures.

Question 2

How much is a Neil Armstrong signature worth?

Accepted Answer

Neil Armstrong signatures range from $600 for basic signed documents to $4,000+ for PSA/JSA-graded photographs on mission-specific subjects. Armstrong stopped signing in 1994 and passed in 2012, making all approximately 55,000 signed items he ever produced permanently finite. PSA/JSA authentication is essential — ungraded signatures are high-risk.

Question 3

What are Apollo 11 crew insurance covers and why are they valuable?

Accepted Answer

Apollo 11 insurance covers are postal covers signed by Neil Armstrong, Buzz Aldrin, and Michael Collins before the July 1969 lunar landing mission. Because life insurance was unavailable to astronauts at reasonable cost, crew members signed postal covers for their families to sell if they did not return. All three Apollo 11 crew members have now passed, making these crew-signed covers one of the most historically significant and scarce categories of space memorabilia. Median price: $15,000–$18,750 based on Gauntlet Gallery's comparable sales data.

Question 4

Is Buzz Aldrin memorabilia a good investment?

Accepted Answer

Buzz Aldrin actively signs memorabilia as of 2025, keeping his signatures more accessible than Armstrong's or Collins's. However, as the last living Apollo 11 crew member, the 'last living' premium will grow significantly over time. PSA/JSA graded Aldrin 8x10 photographs currently range from $400–$1,200. Signed NASA Modern Red Number color photographs have shown a 5-year CAGR of 37.9% per Gauntlet Gallery's comparable sales database.
