Put it inside a tight fitting clear plastic pocket to protect it from further damage, and continue to have it as a pocket piece. Nice coin for such an adventure.
Bit heavy, though. Just make sure that it does not go through the washing machine!
My idea of an ideal American pocket piece would be a common date walker in about MS60. Bit lighter and not so risky, value wise. And more old folk would remember what it is when you show it. Ab. fab. neo classic design as well.
