Production of the new America the Beautiful quarter series continues to run at levels below those that prevailed last year for the District of Columbia and U.S. Territories series.
However, there was an uptick in production of the Yellowstone coin, second design for 2010, from the Hot Springs issue.
A total of 68.4 million Yellowstone quarters were struck, up from the 59.6 million Hot Springs pieces.
Denver Yellowstone output was 34.8 million compared to 29 million for Hot Springs.
Philadelphia Yellowstone output was 33.6 million compared to 30.6 million for Hot Springs.
