State Quarters were released at a rate of five different designs per year for the entire ten year program. The steady stream of new designs released into circulation kept the interest level high for collectors of the series. Each coin release was often coordinated with an official launch ceremony in the state featured, which became a point of pride for citizens.
The first State Quarter featuring Delaware was released on January4, 1999. This was followed by the Pennsylvania, New Jersey, Georgia, and Connecticut Quarters released in approximately ten week intervals. A similar schedule was followed for the subsequent years of the series, with the final State Quarter featuring Hawaii released on November 3, 2008.
Immediately following the conclusion of the program, six additional coins were released during a single year. The District of Columbia and US Territories Quarters Program would honor the non-state jurisdictions of the United States.
The release dates for the entire State Quarters series are listed below, followed by the dates for the DC & US Territories Quarters series.
