After July 1986, Zippo began including a date code on all lighters showing the month and year of production. On the left of the underside was stamped a letter A–L, denoting the month (A = January, B = February, C = March, etc.). On the right was a Roman numeral which denoted the year, beginning with II in 1986.

What do the letters and numbers on the bottom of a Zippo mean?
