A few months ago I found some coins from my grandfather. All of them were worthless, but I found a 1974's Kennedy Half Dollar. As far as I know, some of these are famous because they were struck on a Yuan planchet and are worth some money, but I know nothing about coin and I couldn't possibly know in a thousand years, so I'm here to be enlightened. It is probably a regular half dollar coin, but I'm sure any of you can confirm me. I hope the pics are just fine—otherwise ask me for more. The edge is kind of split in two, with a copperish-like part and a silver-ish one. Thanks!
