Series of 1917 Documentary Stamps and Their Overprints

A Course Presented by Ron Lesher

Wednesdays June 9, 16 and 23 from 4-5:15 p.m. EDT

Did you know that there were three printings of the 1917 documentary stamps?

Course Description:

The cents values of the Series of 1917 documentary stamps were initially printed by Huebner-Bleistein of Buffalo, New York. When Congress objected, the Bureau of Engraving took over the offset printing of these stamps. In 1924, BEP introduced the use of high etch plates to produce these stamps. Learn how to identify these three printings using actual stamps and their overprinted varieties (Future Delivery, Stock Transfer, Silver Tax, Cigarette Tube, Tobacco Sale Tax and Narcotic).

It is known that not all listings exist in the Scott U.S. Specialized for all three printings, so data collected during this course will be used to request an expansion of these listings.

Ron Lesher

Ron’s column “The Tax Collector” has appeared in most issues of The American Stamp Dealer & Collector since its inception in 2006. He has been a collector of U.S. federal and state revenues for about 60 years. Of special recent interest is the inadequate cataloging of the cents denominations of the Series of 1917 documentary stamps and the six other categories of revenue stamps that were created by overprinting these general documentaries (future delivery, stock transfer, silver tax, cigarette tubes, tobacco sale, and the handstamped and press printed narcotic tax stamps) that were in use from 1917 to 1940.
