When I was a kid in the 50s visiting my grandparents in Idaho, my grandfather would pull Morgan silver dollars out of my ears. He always gave them to me after “finding”them there. Unfortunately, I spent them all in my teens. Ouch.
Silver Dollars were still in circulation in Nevada and Idaho in the 50s. When I was little I remember my dad taking me into a bar in Idaho. The long bar had 100s of silver dollars embedded in it. Not likely there any more.
