38 Star-Concentric Oval or Medalion Flag-1877
In August of 1876, Colorado, the Centennial State, joined the Union, bringing the number of states to 38. In accordance with the Flag Act of 1818, the 38 Star Flag became official on the next 4th of July.
The concentric oval or medallion design became popular. A few from the late 1870’s still exist in private collections. In 2000, the Postal Service honored the 38-star Concentric Oval Flag with a 33-cent postage stamp.
