Reverse
Five different state commemorative reverses: Delaware, Pennsylvania, New Jersey, Georgia and Connecticut.
All five 1999-S state quarter Proof coins belong in this regular 9-coin clad proof set. The old heraldic eagle reverse was discontinued for this series. The five quarters are grouped on one web page for this archive.
04 FIVE STATE DESIGNS
Delaware · Pennsylvania · New Jersey · Georgia · Connecticut
The 1999 standard U.S. Mint Proof Set has five different Washington quarter reverses, not the pre-1999 eagle. This single denomination page documents all five 1999-S clad issues.
