King's mountain military coin

Does anyone know anything about the age or value of such a coin

Just perform a Google search

Have but really haven't had much luck

It's a souvenir from Kings Mountain National Military Park in South Carolina. Unless you somehow find a collector looking for this exact medallion, it's unlikely to fetch any kind of premium. And even then I wouldn't expect it to have any kind of significant value.

Thank you to Frenchlover's link, by the way. All of the information needed was a click or two away.
