As with most collectibles, the date of manufacture of a Zippo lighter often affects its value. Starting in the mid 50s, a date code was stamped on the bottom of every Zippo lighter made. The original purpose was for quality control. The date code has since become an invaluable tool for Zippo collectors.

Is Zippo waterproof?

Durable design: Unlike many butane lighters, the Zippo design protects all the weaker parts. A Zippo can handle being stepped on, dropped or being stomped into the mud. If the lighter is sealed with a piece of bicycle tubing, it is waterproof.

How long should a Zippo wick last?

Wicks should be replaced once or twice a year. Each wick is almost four (4) inches in length, so after 2-3 trimmings youll need to replace the wick. The wick should be changed if the lighter does not lighter properly or if the ignition process has to be repeated multiple times.
