Looks like a 69 cal.
69 cal musket ball was one of the earliest. They then converted the 69 smoothbore(musket ball) to the 69 cal rifled barrel for the Minie/3 ringer(yours). They then determined the 58 cal to be more accurate and that caliber was the most popular and used throughout the war....although even other calibers were used.
More than likely yours has to do with the civilwar. It is a nice addition to your collection. Not real common. Actually most of the troops didn't like them and would pick up a 58 off the battlefield the first chance they got. Oftentimes the 69 would black their eye or even break the clavical bone.
