19th Century U.S. Cancellations

A 2-Day Course Presented by Roger Curran

Monday, June 22 – Tuesday, June 23, 2020

When the Post Office Department first introduced stamps in 1847, postmasters had a new responsibility, one of canceling stamps to prevent reuse. Their decisions and practices over the years produced a remarkable variety of cancellation types, designs, sizes, and colors.

Course Description:

As you trace the evolution of U.S. cancellation approaches from 1847 – 1900, you will learn how stamps were canceled and why postmasters used different practices over time. Major innovations will be highlighted. Attention will be given to cancels typical of each of the several time periods involved. Historical context will shed light on the decisions made by postmasters.
Enjoy two days discussing the principal factors that resulted in the use of the various types of cancels. Through examination of representative cancels, you will gain a deeper understanding of this era and enhance your identification skills.

Intended Audience:

Those with a particular interest in U.S. cancellations.
Those who collect 19th century U.S. stamps and/or covers.
Those with an interest in U.S. postal history.
