Douglas Brown of Virginia sent in a 2009-P District of Columbia quarter that shows heavy die deterioration doubling on the lettering around the obverse rim.
It is strongest on UNITED STATES OF AMERICA. There are die breaks on Washington’s forehead and a crack above the eye.
The reverse is also very heavily deteriorated with many die chips and breaks especially throughout the date, UNUM and letters above.
Additional die chipping is seen on the piano keys and areas below furthest to the right.
Die chips and breaks like this are considered very minor and specialists essentially ignore die deterioration doubling as inherent to late die state coins. Nonetheless, coins with as many die breaks and die chips as this one are fun to find and collect even if their values are nominal.
