stamp date
codes as with most collectibles, the date of manufacture of a zippo
lighter often affects its value. valuable information on the bottom of every zippo lighter can help you determine its date of manufacture. most lighters fabricated between 1933 and 1957 can be identified by style and model and the patent or patent-pending marks. starting in the mid 50s, date codes were stamped on the bottom. the original purpose was for quality control. the date codes have since become an invaluable tool for zippo collectors. the appearance of the word ?zippo? in the bottom stamp provides another clue to dating. there have been three major changes, as shown in inset. from 1933 to the mid 50s the word zippo was stamped in block letters. the zippo script logo was developed in the late 40s and was phased-in on the lighter bottom stamp around 1955. in the late 70s the logo was redesigned. it was incorporated into the bottom stamp in 1980. ® (1980 - present) (1955 - 1979) (1933 - 1954) on some lighters, this number was stamped in error, should have been patent 2032695. zippo records indicate an overlap of bottom stamp configurations from 1949-1957. some lighters produced between 1955-57 were date coded; however, specifics remain unclear. in 1979 an error was made in the date code. one of the slash marks was removed from the left of the zippo trademark instead of being removed from the right; thus the code read: / //. this date code error was corrected within the same year to read: // / effective july 1, 1986 the dot and slash system was replaced by year / month code. year is coded by roman numeral; letter designates month (a=january, b=february, etc.) beginning in 2001, the roman numerals indicating the year were replaced with numbers corresponding to the last digits of the year of manufacture. the first zippo blu ® butane cases were made in 2005. the date code is the same format as regular windproof lighters. * code is subject to change without notice. 1 2 3 4 5 6 7
