National Marine Sanctuaries Stamps 2022 First-Class Forever Postage Stamps

In 2022, the United States Postal Service celebrated the 50th anniversary of the National Marine Sanctuary Program with a set of 16 Forever stamps.  Each one pictures scenes from different sanctuaries in the system.  As of early 2022, there were 15 designated national marine sanctuaries and two national marine monuments, protecting over 620,000 square miles of US waters.  Most of these are located in the Atlantic or Pacific Oceans, but two are in the Great Lakes. They showcase the abundant wildlife, scenic beauty and underwater archaeological treasures found throughout the sanctuary system.
