I've been buying and selling them for a while & I don't know where you can look up the serial numbers, if at all. It would be very useful but on the other hand, if it were easily accessible, there's nothing to stop the determined faker from copying e.g. Ligne 2 models & using genuine corresponding serial numbers on them.
ST Dupont may have a record of all the lighters they've produced. Ligne 1, 2 and ' D ', Gatsby, Urban, models have hand-stamped serial numbers, not machined. They are irregular and not perfectly aligned.
The S.T. DuPont lighter serial number 50 is located on the bottom. Each letter and number is printed separately so that each one differs.
100 dollars
The address of the Dupont Library is: 1540 Wilmington Drive, Dupont, 98327 M
This is the thickness of the gold plating on the lighter. 20u would be 20 microns
The average price of a used Dupont lighter very much depends on the model that you want/have. Depending on the model they can sell for anything between $20 and $15,000
According to a specialized dealer only Line 2 and Gatsby Duponts are made to ping.
