For those interested in the Daguerreotype market at auction, albiet vintage ones, here’s some news via Alex Novak’s E-photo newsletter (http://www.iphotocentral.com). Sothebys regular spring sale had a record sale of a Daguerreotype:
"Pierre Apraxine, consulting on his cell phone, captured a half-plate
daguerreotype, Albert Southworth & Josiah Hawes’s Portrait of Samuel Appleton,
circa 1850, for $409,000, the second highest price of the sale, more than four
times its top estimate of $90,000, and setting a new record for the artists as
well as for an American daguerreotype at auction. But the new record was set
only because of Sotheby’s new higher premiums."
