1933-34 Century of Progress Expo

Set Description
The 1933 World's Fair was held in Chicago. The theme was 100 years of advancement in science and technology. The fair was originally supposed to run only in 1933, but only half the bonds were paid off. It reopened in 1934 for a second year and successfully retired all its debts, the first world's fair to do so.

Set Goals
Hibler & Kaplan limited their so-called dollar listings to medals measuring between 33-45 mm. Most of the medals struck for this fair were 32 mm or less, so they were not listed. There was a more detailed catalog of Century of Progress Expo medals that includes the sub 33 mm ones. It was in the Journal of the Token & Medal Society, Volume V, Aug-Oct 1962, Number 4. It was compiled by Nathan Eglit (Columbania). It uses CP prefixes as identifiers. The publication is readily available on the internet.
