They will never be worth less than face value. http://catalog.usmint.gov/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&storeId=10001&productId=14536&langId=-1&parent_category_rn=10211 The 2008 United States Mint Uncirculated Coin Set® contains two folders of 14 coins each, one from the United States Mint at Denver and the other from the United States Mint at Philadelphia, for a total of 28 coins. Each folder includes uncirculated versions of the following 2008-dated coins: four Presidential $1 Coins honoring past Presidents of the United States: James Monroe, John Quincy Adams, Andrew Jackson and Martin Van Buren; the final five quarters from the 50 State Quarters® Program: Oklahoma, New Mexico, Arizona, Alaska and Hawaii; and the Lincoln cent, Jefferson nickel, Roosevelt dime, Kennedy half-dollar, and Golden Dollar featuring Sacagawea. Uncirculated coins are struck on special presses using greater force than circulating coins, producing a sharp, intricately detailed image, and feature the satin finish introduced in 2005.
