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
I have one also on the front side under the head it’s not a uniform circle it’s higher on one side. ericsargent69@yahoo.com
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.
I have a 2013 silver fort mc Henry quarter . On the head side of the quarter at the bottom the edge of the coin is like mis stamped. The edge of the coin is higher in one spot. Does anyone know anything about this. It’s very shiny to.
I have 1 where the edge of the coin underneath the head is raised up higher on one side of the coin. The coin is very shiny. Does any one know anything about it. My email is ericsargent69@yahoo.com
