2015 U.S. Mint 14-coin Silver Proof Set - OGP box & COA

• 7 of  the 14 coins included in the 2015 United States Mint Silver
  Proof Set are 90% silver.
• This set contains 14 coins in proof quality, protectively encased in
  three clear plastic lenses and newly designed packaging.
• The 2015-dated
  quarters, half-dollar, and dime are struck in 90 percent silver,
  generally referred to as “coin silver.” The silver in these coins can be
  seen by viewing the edge of the coin in the lens.
• U.S. Mint proof coins feature sharp relief and a mirror-like background.
  Their frosted, sculpted foregrounds give them a special cameo effect.
  Proof blanks are specially treated, polished, and cleaned to ensure high
  quality strikes. The blanks are then fed into presses fitted with
  specially polished dies and struck at least twice to ensure sharp
  relief. The coins are then packaged in a protective lens to showcase and
  maintain their exceptional finish.
