Following up on John Lupia's biography of Edward Cogan, presented in last week's E-Sylum, the Newman Portal has completed scanningof the Edward Cogan auction catalogs. Both Adams (United States Numismatic Literature, Volume One) and Gengerke (American NumismaticAuctions) count 70 Cogan sales, from 1858 to 1879, and these are all now available on the Newman Portal. This set was primarily scanned at theAmerican Numismatic Society library, with Dan Hamelberg filling in key items at the end, notably a manuscript copy of the Foote sale (3/7/1859), andthe DeHaven collection catalog (1861, sold en bloc to Lilliendahl).

The DeHaven catalog was little known to us - we used the Newman Portal itself to search on "DeHaven" and located information from John Adams on this rare Cogan emission. The Cogan series further features the first plated catalog in American numismatics, namely the MacKenzie collection (1869), and the ANS copy presented here is a triple play - plated, priced, and named.
