This is a Shield Nickel that split in half. Sure wish I had the other half to go with it. A great early split planchet.
I have a War Nickel that split. It's graded and I have both halves to that coin. This Shield Nickel is nice due to the age.
I've never tried but I would think so. For the ones I have and have seen, they all have the same appearance. The metal looks as if it wasn't bonded (so to speak) together correctly.
