Coin Challenge - Boots

This coin challenge shows feet encased in laced boots taking a stride. 

What is the coin? Is it silver, gold or another metal? Did the coin circulate or is it a commemorative coin? What is the denomination - a penny, nickel, dime, quarter, half dollar, dollar or another coin from early coinage? Is the design from the obverse or reverse of the coin? (Scroll down for hints.)

Hints:

1. It's a commemorative coin.
2. The military person wearing those boots is also wearing fatigues and carrying a gun.

Several of our commemorative coins recognize and honor our military. But, which coin has the military in fatigues, walking and carrying a rifle?

1. The scene, including the military boots, portrayed on the coin occurred in 1957.
2. A picture of the entire coin can be found on one of the web site’s pages for coin sets.
