What's up with this half?
Hey coin community, I came across this half dollar last night. It looks to be a gold-plated 1967 Kennedy half, however it seems to have a problem...
It doesn't ping like a 40% half dollar. The ring sounds like a cupronickel planchet (though I know it couldn't be as they weren't even manufactured for four more years), maybe an even higher tone than that. It has to be a 40% planchet, right?
My question is, well, what the heck is going on with it? Do you think whatever gold-plating process that was used somehow messed with the composition? Why doesn't it sound like a silver planchet?
