A single book that sold for over $100,000 was among the items that sold at the auction.
The auction of more than 1,000 of Ginsburg's books and other manuscripts generated bids that were beyond our wildest dreams, according to Catherine Williamson, specialist of fine books and manuscripts at Bonhams, which sold the collection.
In a phone interview, she said she thought the auction would be between $300,000 and $500,000. She told CNBC after the auction ended that the total sum of all final bids was $2,354,510.
The online auction ended Thursday afternoon, the same day that Justice Stephen Breyer announced he will step down from the bench.
Most of Ginsburg's items had previously been sold at auction, so Bonhams was deliberately conservative in their estimates. The late justice brought a flood of attention and bidding interest to potential buyers that were younger than the Bonhams regular crowd of book collectors.
