"I think it is incredible that this small check signed by Neil Armstrong has sold for such a fantastic price exactly 40 years to the day that it was signed," said Bobby Livingston of RR Auction www.RRAuction.com of Amherst, NH, which held a 17-day online auction of the check.

Bidding lasted until 8 a.m. today (ten hours beyond the intended auction bidding deadline), and is the most expensive single signed Neil Armstrong autograph ever sold, according to Anthony Pizzitola, Vice President of the Universal Autograph Collectors Club, breaking the record of $19,000.

The check was purchased by Jack Staub, an engineer and business owner from Newport Beach, CA.

RR Auction obtained the check through Noah Bradley, who bought it at auction from Harold Collins' son George in 2004. George Collins told Bradley that on the morning of the launch, Armstrong realized that he owed Harold Collins, NASA Chief of Mission Support, $10.50. He made out the check and told Collins that it should be cashed ONLY if he died in space.

The only known Apollo-era check of Armstrong's, its signature includes his middle initial and is one of only a handful of items signed in full by Armstrong, who has not given an autograph since 1994.

"This is probably the coolest Apollo 11 autograph in private hands," Livingston said. "Here's Neil Armstrong rocketing to fame, and he wanted to make sure that he paid his debts in case anything happened."
