The first comprehensive collector's guide or reference work on the classic US commemorative series was authored by noted numismatist Howland Wood, it was entitled
The Commemorative Coinage of the United States and was published by the
American Numismatic Society (ANS) as part of its ongoing "Numismatic Notes and Monographs" series (it was No. 16).
The small booklet was published in 1922 and covers the commemorative issues from the 1892 Columbian Exposition half-dollar through the 1922 Grant Memorial gold and silver coins. It begins with a brief introduction/background to US commemorative coinage and then proceeds to discuss each coin issued through the time of its publication; for each coin, the text of its authorizing legislation is included. Each coin is illustrated (in actual size) via a series of plates at the end of the volume.
I always enjoy reading through early literature on the classic commemorative coins to gain insights into how the series was viewed during its active issuing period. In the case of the Wood booklet, information on each coin is presented in a neutral, academic style void of personal views or commentary. It's a great little book, I was happy to find a nice copy a few years back so that I could add it to my commemorative library.
The book can be a bit difficult to locate and can be a little pricey when it is, but its place in US commemorative literature history makes the effort and expenditure worthwhile (IMHO)! And who knows, diligent searching may uncover an inexpensive copy!
