2014 United States Mint Silver Proof Set - 14 pc set, about 1 1/2 ounces of pure silver. The 2014 set contains 14 of this year's coins struck in stunning Proof condition, including five America the Beautiful Quarters, a Roosevelt Dime and Kennedy Half-Dollar in 90% pure silver, plus seven additional coins in Proof condition! Housed in their official packaging and accompanied by a Certificate of Authenticity from the U.S. Mint, this annual set is a perennial sellout, and a favorite of collectors new and old since they were first issued in 1992. Why? Because these one-year-only sets contain the absolute best of the best of U.S. coins! Proof struck coins are the ultimate in quality, beauty and value! Double-struck under intense pressure to bring out the high-relief details and dazzling luster, proofs have distinctive mirror-like backgrounds and frosted sculpted foregrounds.
