Since the U.S. Mint began offering the 5-ounce silver bullion coins beginning with the 2010 issues, combined sales have reached 1,251,900 coins (6,259,500 ounces). 

The highest sales recorded for individual coins were 126,700 each for the 2011 Gettysburg National Historical Park and 2011 Glacier National Park 5-ounce silver bullion coins.

The lowest individual mintages recorded are 22,000 each for the 2014 Arches National Park and 2014 Great Sand Dunes National Park coins.

2014 is also the year the U.S. Mint established a sales record for American Eagle 1-ounce silver bullion coins at 44,006,000 coins, a record that was eclipsed Nov. 30, 2015, with the number for 2015 still climbing.

The U.S. Mint sells the 5-ounce silver bullion quarter dollars through its network of authorized purchasers for eventual resale to other dealers, collectors and investors. The Mint’s selling price is based on the closing London PM spot price per troy ounce plus a premium of $9.75 per coin.

The coins are struck without Mint mark at the Philadelphia Mint. 

The U.S. Mint also strikes an Uncirculated numismatic version bearing the P Mint mark. The Uncirculated versions are offered at a fixed premium above the intrinsic value of the precious metal each coin contains. The price of the Uncirculated versions are subject to fluctuations in the price of the precious metal.
