After eleven successfull years of Collectible of the Year Zippo Manufactoring Company in Bradford, USA decided to cancel the series of collector lighters. The follow-up had to be the Z-Series.
Z - Series is an internal used concept and means 'pre - production'. These ZIPPO-lighters are prototypes for special materials or finishes - anything that's possible.
Till now these prototype had been destroyed, were stored at the archives or exposed at the ZIPPO-museum. With the new Z-Series a new age of collecting lighters began! This first Z-Series is a series of lighters made of pure copper. While pre-production it happens with some lighters that they have minor errors otherwise to the final production. With this errors every lighter is unique.
Totally 21.441 lighters were produced. Each lighter has a special Z-Series bottom stamp and a Z-Series identifier on the body. Those 21.441 lighters have a limited number on the side as follows:

• 10.188 pieces for the US-market code "A"
