Sanborn Auctions Kryptos Part Four Solution at RR Auction

🔐 Jim Sanborn is auctioning the original solution to Part Four (K4) of his Kryptos sculpture, with RR Auction estimating a winning bid of $300,000–$500,000 for the lot. The sale, scheduled for Nov. 20, includes the handwritten plaintext, related papers, and a 12-by-18-inch copper proof-of-concept plate with 1,800 hand-cut letters. Sanborn hopes the buyer will preserve the secret and assume verification duties, potentially by implementing an automated review process.
