Date and Patent codes are key to dating vintage Zippo lighters
Blaisdell had date codes imprinted on the bottom of the lighter cases. These codes provided him with the date of manufacture, should a defect be found, allowing him to maintain records of repairs. Fortunately, those date codes are a tremendous help today in the ability of collectors to correctly identify the year any given Zippo lighter was made.
Other factors for dating early and vintage Zippo lighters are their height and shape, the number of barrels on the hinge and the case’s material. Inserts can also be dated by their material, number of holes in the chimney, flint wheel style, cam style and markings.
Very quickly, you can determine a broad age of a Zippo lighter based on the three major changes to the style of the word “Zippo” imprinted on the bottom of the lighter. The “Block” Zippo was used from 1933 to 1954; it was changed to the “Script” Zippo in 1955, and the “Flaming i” began in 1980.
Pat. Pending was stamped from 1933 until the end of 1936, when it was replaced with Pat. 2032695. Pat. 2517191 was stamped from late 1953 until 1967.
Date codes appeared as early as 1955, and the dating system was fully in effect by 1959. Before 1959, dating Zippo lighters can be a bit tricky, as the exact placement of the words must be taken into consideration. We’ve provided examples of what we believe to be the correct bottom codes for those tricky years. Again, placement of the wording, the material the case is made of and the number of barrels on the hinge play key factors in dating earlier Zippo lighters.
In 1986, the dot and slash date code methods were replaced with Roman numerals representing the year and letters of the alphabet representing the month of production.
In 2001, the last two digits of the year were used along with the same letters for the months, and that system continues today.
Slim Zippo lighters were introduced in 1956 and had no date code on the bottom of the lighter. Slims were first marked in 1957. From 1957 through 1965, slims had different bottom date codes than did regular size Zippo lighters. Beginning in 1966, the same markings were used on both the slim and regular. In 2002, the holes in the chimney of slim lighters were enlarged.
Dating Zippo lighters produced in Canada from 1950 until 1986 is difficult due to the lack of date coding. The bottom stamps shown here generally provide for time spans.
