The Semiquincentennial (Olympia Roundup Show) - Olympia, WA
The Semiquincentennial
As the United States approaches July 4, 2026, the nation prepares to celebrate its Semiquincentennial, marking 250 years since the signing of the Declaration of Independence. This milestone is more than just a birthday; it is a reflection on the “Great American Experiment” and the evolving journey toward a more perfect union. For collectors in the Olympia Philatelic Society, this anniversary provides a unique opportunity to document history through the tangible medium of stamps and coins.
These items have long served as tiny windows into the nation’s soul, capturing the leaders, innovations, and landscapes that define the American experience. By hosting the Roundup Show in 2026, the society honors the enduring legacy of 1776 while fostering the continued preservation of our shared heritage.
