I have a box of "vintage" Montecristo 10-Rothschilde Habana 2000. The box is unopened and is years old. I don't know how to find the date of packaging, but I was told that it was old. Someone wants to sell them for me, but I have not a clue as to what the value might be. I've seen empty cigar boxes, but I've not seen an old unopened box before. Could someone venture to say what value I might ask and thank you so much!
