Last weekend, Ken Sanders, a rare book dealer in Salt Lake City, volunteered to serve as an appraiser for a local museum. People paid $2.00 to have him look at their old books. “Usually these appraisals are one long exercise in telling people there’s no way they can retire on their old book collections,” he said. But this time was different. A man brought in what Sanders believes is a copy of the Nuremberg Chronicle, published in 1493 and considered one of the oldest illustrated books in existence. If found to be authentic it could be worth $100,000.
