The 2006 Colorado Official First Day Coin Cover is the 38th in the series. This limited-edition cover -- only 50,000 will be produced -- features two Colorado quarter-dollars from the first day of mintage, May 8, 2006.
Each cover includes two quarters, one each from the United States Mint at Philadelphia and Denver, on a handsome display card with the 39-cent United States Lady Liberty and Flag postage stamp. The postmark of June 14, 2006, Morrison, Colorado, marks the day the Colorado quarter-dollars were first released to the Federal Reserve Bank and to the public.
