I'm at my grandfather's house, looking through his coins, and found something odd. A Kennedy half from 1965 with copper on the edge. It weighs about 11.3 grams. I know that they were 40% silver during this year, but I found it quite odd. I'll try and post pictures later. Any thoughts?
You sure about that? I have a bunch of other 40%ers and they are all silver on the edge. This one is bright copper
They are clad, with outer layers of .800 silver and .200 copper bonded to an inner core of .209 silver and .791 copper.
I have found several 40%ers that look like that. You are right, most don't, but some do. Nothing special.
