Probably the silver lol. I don't think my dad was a Kennedy fan but he had quite a hoard of silver ones
Years back, a couple of companies sold "shotgun" rolls for a reasonable amount, so many of us older collectors have at least one roll left. I think your dad was one of those also.
He just had it wrapped in paper. It was mixed with all of coins. That’s how I came to the others. Probably not touched for, well a long time.
