The American Numismatic Association has announced the winners of its ANA Member Volunteer Challenge, which took place in conjunction with National Coin Week from April 20 to April 26 and celebrated the 50th anniversary of the Kennedy half dollar. The week-long celebration also honored President John F. Kennedy's famous call to civic and community service: "Ask not what your country can do for you, ask what you can do for your country.”

ANA member Charles Corrado won the grand prize, a Proof 2014-W American Eagle quarter-ounce gold coin, for documenting his efforts volunteering with the Arizona-based environmental organization Friends of the San Pedro River. 

Second prize, a Proof 2014-P Civil Rights Act of 1964  silver dollar and 2014-S America the Beautiful Quarters Proof set, was awarded to Jenna Van Valen for her volunteer work at St. Mary's Home for Boys in Oregon. 

Ernest DiMeglio won third prize, a Proof 1996-S National Community Service silver dollar and 2014-S America the Beautiful Quarters Proof set, for his efforts in helping visually impaired veterans at a Veteran Affairs clinic in New Jersey.
