The Denver Guam quarter is now the scarcest of the new 2009 designs, with a total production of 42.6 million pieces, a figure that is less than half the number of the District of Columbia and the Puerto Rico issues.
For Philadelphia, the Guam mintage total dropped almost as low to 45 million coins, but because the Puerto Rico output was just 53.2 million, the decline was not as large percentage-wise. The Puerto Rican P-mint mintage was the prior lowpoint this year.
Since the beginning of the year, the pace of quarter production has dropped by half.
There were 88.8 million Denver District of Columbia quarters and 83.6 million Philadelphia D.C. quarters struck.
For Puerto Rico, the Denver mintage total was 86 million, almost as many as the D.C. total.
The rate of output is running at a low level not seen since the 1950s.
Three more designs will be coined this year, American Samoa, U.S. Virgin Islands and the Northern Mariana Islands.
The question is will one of these next three designs from one of the two mints have a mintage total to rival the 6.36 million of 1958 Philadelphia or the 3.182 million of 1955 Denver?
