An Apollo 11 lunar surface checklist sheet was among the coveted items sold at a New York City auction of space exploration artifacts.

The checklist contained annotations by astronaut Buzz Aldrin while he was on the moon. It sold at Bonhams on Tuesday for more than $68,000. It had a pre-sale estimate of up to $45,000.

Other highlights included a 6-inch cloth emblem depicting an eagle landing on the moon. Bonhams said the Apollo 11 emblem did not travel with the crew during the mission but was signed by Aldrin, Armstrong and Michael Collins. It sold for more than $62,000.

A U.S. flag carried by Aldrin on Apollo 11 fetched $47,500, double its pre-sale estimate, and a Mercury-era spacesuit garnered over $43,000, more than five times its estimate.
