This is a beautiful walking liberty half dollar from 1942 in an original first generation pigs holder. The coin was designed by A. Weinman, who also designed the mercury dime coin from the same era.
The coin has a little bit of nice blue toning on the reverse; I took multiple pictures of the back so that you can see the color gradient. If you collect walkers, old pcgs holders, or just beautiful coins, this is an excellent piece to add to your collection!
