San Francisco's Worlds Fairs and Expositions

Set Description
This is a collection of exonumia from the several events held at San Francisco over the first half of the 20th Century. This will concentrate on the well known 1915 Panama-Pacific International Exposition, as well as the lesser know 1909 and 1913 Portola Festivals. It will also include some pieces from the 1894 Mid-Winter Exposition, and probably (later) the 1939-40 Golden Gate International Exposition (aka the Treasure Island Fair). The basic problem however, is that a large minority of tokens and medals, as well as all of the badges, etc., from these events are either not cataloged, and therefore not certified by NGC or PCGS, or not suitable for encapsulation; as such, much of the collection cannot be listed here in the NGC Registry, but it is a start. I welcome communication from other interested parties on the subject.

Set Goals
Tokens and medals from the World's Fairs, Expositions and related events held at San Francisco, California, 1894 to 1940.
