Unfortunately, positive identification of these historic rarities could never be made until now. The Louisiana Secession Seated Liberty Half Dollar comes authenticated and slabbed by NGC, with a Certificate of Authenticity in a hardwood display case, accompanied by your personal copy of the National Geographic DVD ?Civil War Gold.?
