The US mint released the Fort McHenry Quarter August 26, 2013, the 26th release of the America the Beautiful series. The quarter portrays Fort McHenry on the coin’s reverse.
There is doubling on the reverse of some coins. Most errors occur in the firework flash, pictured below.

Additional double die errors can be noticed along the building edge in the center, near the bottom of the waving American flag, and along the windows of the left-center building. Additional images coming soon.
I would love to show you a picture of a less than uniformed circle on the front side of a quarter I have. Email me for pictures.
Sincerely,
Jeremy
There Is doubling on the 2013
What about instead of having 13 stripes on the flag, it has 15 stripes. Major error.
Not an error the Flag at that time had 15 stripes, the coin is historically accurate
I count 15 stripes on the flag of my fort mchenry quarter, too.
