These sterling silver buttons are hand hammered into a two part tool steel die. I made the steel die for these buttons about 40 years ago when I was a blacksmith. It can make 1/2" and 5/8" buttons. Set of five sterling silver hogan buttons pictured $30. They are 1/2" in diameter. Traditional Navaho design named after shape of hogan dwelling. Also available in 5/8 inch size ($30/set of five).
