Greg Bennick Interviews Stan Kesselman

Stan Kesselman, a NY coin dealer, worked parttime in numismatics without a store front, quietly trading between the leading dealers and collectors of the day, beginning around 1960. Among his clients were the well-known collectors Harry W. Bass, Jr., R. L. Miles, Ted Naftzger and others. Kesselman specialized in rare date U.S. gold and was involved in transactions such as the purchase of the Naftzger $20 Liberty set, complete from 1850-1907.

Greg Bennick has interviewed a number of numismatic personalities for Newman Portal, capturing stories to inspire the next generation of numismatists.

Julius Guttag Latin American Catalog

The 1929 publication of Catalogue of the Collection of Juilus Guttag: Comprising the Coinage of Mexico, Central America, South America and the West Indies described nearly 5,000 types of Latin American coins and effectively served as a forerunner of the well-known Standard Catalog of World Coins. Although serving a catalog of the Guttag collection, the work is properly credited to Edgar H. Adams, of whom Guttag writes “Mr. Adams has done all the work of preparing the catalogue…I cannot thank [him] sufficiently….”

Among the many treasures of the American Numismatic Society Library is a five-volume set containing the individual pages of the Guttag Catalogue along with the pasteups of the original photographs. The quality of these images is generally much better than the halftone reproductions in the published version. This five-volume set has recently been scanned and is now accessible via Newman Portal.

The Guttag Latin American collection was sold in parts, with the first installment appearing in Kosoff’s December 10, 1941 sale. Part X, apparently the last, was featured in the Kosoff October 24, 1942 sale. Kosoff references individual coins by the Guttag number, allowing for comparison with the published reference. Kosoff further sold the Guttag library (August 6, 1940), but these five manuscript volumes do not appear in auction sale catalog.
