2014 50th Anniversary 4-coin Silver Kennedy Half Dollar Sets

In honor of the 50th Anniversary of the Kennedy Half dollar's initial minting, the U.S. Mint released the special 4-coin silver Kennedy half-dollar sets.

Each set includes the following coins:

• One reverse proof coin from the U.S. Mint at West Point
• One proof coin from the U.S. Mint at Philadelphia
• One enhanced uncirculated coin from the U.S. Mint at San Francisco. This is a special wire brushing technique implemented in Philadelphia for the first time.  The obverse in the areas of the effigy (portrait), lettering, and border will all receive a heavy laser frosting treatment. On the reverse, the lettering and border will each receive a heavy laser frosting treatment.  Other elements of the eagle will receive a standard (moderate) laser frosting treatment to enhance certain artistic detail. The stars will receive a laser polish technique to accentuate them against the field.
• One uncirculated coin from the U.S. Mint at Denver
