ANTI-COUNTERFEITING PATENT INFORMATION SOUGHT

Dave Bowers writes: "In connection with a book I am writing I
desire to correspond with anyone who has information regarding
some of the more obscure patents and processes regarding anti-
counterfeiting. I do not need the Rawdon, Wright, Hatch & Edson
?green tint? of 1857, or the National patent of 1860, or any of
Perkins? patents, or Lyman?s or Seropyan?s patent.

I would like to learn more about the Congreve Patent Check Plate
(used in the USA by New England Bank Note Co., perhaps related to
Sir Wm. Congreve of English bank note renown), Star?s patent,
Desopyn?s patent, Atwater?s patent, and any related patents.
Many of these arose in the 1850s when there was a scare about
photographic counterfeits of bank notes.

Also, if anyone has some paper scrip notes of New York City,
fractional amounts, with dates from May through August 1837, I
would be desirous of obtaining some images.

Thanks to anyone who can help! Will be in Atlanta at Whitman
this coming week, and Thursday and Friday at the ANA Money Show."
