If the ones in the black box are "Gran Reserva" (15 count) then you have something special there. Those are worth about $1500 a box. Just keep in mind that 90% of Cuban Cohibas out there are fakes. There is also a much cheaper (price & quality) US-friendly Dominican variety. The Dominicans will have a black/white label,with the "O" filled in with red. Post good pics of the box/labels (including the bottom stamp) if you can.
