St Dupont Lighter Serial Number 4fk12j8
Posted on
For sale, a genuine* vintage, gold-plated ligne 2 ST Dupont, in very good working condition. Serial number 9 U B K 3 8.
This is in good overall cosmetic condition. There are signs of wear in keeping with its age - I'd put this at around late '70s. Part of the hinge on the flame adjuster, located on the bottom, is missing. This doesn't affect the ability to adjust the flame fully by pushing the remaining half of the hinge with a small screwdriver, cocktail stick etc.
The lighter was serviced round about February and it's been lit regularly since to keep things lubricated; the lid snaps shut smartly, and opens with the much talked-about ' cling '. Music while you puff, the best of two worlds. Everything works just as it should - beautifully.
This lovely, reliable Dupont will be posted special delivery, next working day.
*Beware - there is an absolute rash of fake Dupont lighters being offered for sale on Ebay right now. Some are very convincing and need closer scrutiny, but there are oft-used signs that give away many counterfeit items. Fake serial numbers: one widely-used is 4FK12J8. This isn't the only number/letter combination used, but most fake serials are machine-stamped with perfectly-aligned letters/numbers rather than the irregular, unique hand-stamp on each genuine ST Dupont. These cheap fakes sell for £200+ on occasion - I saw one seller get rid of them to the tune of £1000+ in a matter of four or five sales last Christmas. If the serial number is stamped to the same depth as other words on the bottom plate this is suspect. There are a few around now that, whilst being ' new ' items, have unusual serial numbers that don't look right. It appears an effort has been made on some dubious-looking glitzy lighters to make the number deliberately look irregular, though it's amateurish and still machine made and the characters too large in some.
Each serial number is unique to that item and on record with ST Dupont.
Some counterfeits now include the ' Leaf ' symbol that is found on many Chinese lacquered models. If a lighter says ' Laque de Chine ' it stands to reason there should be some Chinese lacquer on it and not be plain gold or silver. Ligne 2s, limited editions and particularly James Bond ligne 2s are often faked. There are copies of limited editions such as the Shaman & Nuevo Mundo: one copy of the latter very recently sold for nearly £200 - a sum that could buy a very nice genuine ST Dupont any day of the week. Others defy any identification simply because they don't exist. Limited edition items won't have a regular serial number - they have the number of items made, e.g. 2500 and the individual number in the series of that item, e.g. 405/2500. There's a good website called where many photos of real limited edition pieces are visible. These are helpful in separating the glamorous-looking fake from the real deal. The old Ligne 1s are more or less untouched by fakers. I've not seen a Ligne D fake, either. Feel free to mail me on here if you have any questions, or would like me to have a look at an item you're considering - I'll gladly offer any pointers I can.... read more
This is a short guide on how to quickly determine if your S.T. Dupont Linge (Line) 2 Lighter is authentic. These are the lighters most 'faked' on Ebay. There are also counterfeit Gatsby lighters I have seen on Ebay as well. Usually persons selling have little to no feedback, 100 points or less. A lot are from China, but it isn't hard to setup an account to make it look like your somewhere your not. Also the selling party might not even realize that the lighter is a fake, the Line 2 counterfeit lighters look exactly like real ones, depending on model/design being counterfeited. This is in good overall cosmetic condition. There are signs of wear in keeping with its age - I'd put this at around late '70s.

Dupont Cigarette Lighters Price Guide
If the selling party does not picture the bottom of the lighter, where the serial number is, its Probably fake.

If it looks the the numbers are lined up perfectly, if they are engraved, its fake. ST Dupont stamps their lighters with numbers not aligned in a straight line, some numbers looking higher or lower then others. Counterfeited line 2 have serials engraved in a straight line. Even if your lighter doesn't look like one of the lighters pictured below it still could be fake. Fakes change on a regular basis to try to keep up with ST Dupont.
Top gold lighter is Authentic, bottom silver color is FAKE
Serial should never start with 4FK as fakes many do.
Some new Fake ST Duponts now have a Chinese lacquer leaf on the bottom. If you compare to a leaf from an authentic ST Dupont, it differs.
The Instruction manuals are different in color then the Genuine instructions.Some new Fake ST Duponts now have a Chinese lacquer leaf on the bottom. If you compare to a leaf from an authentic ST Dupont, it differs.
top instructions (yellowish) are genuine warranty card on the left is genuine, its not as dark as the fake
Its also possible to place a fake ST Dupont lighter, in a genuine box. I have seen it done several times on Ebay.
The insert in the gift boxes have sharply raised angled edges, genuine boxes have only very slightly raised edges, almost hard to notice in most pictures. Also you can notice the color difference, though my camera isn't perfect when representing true color.
All pictures the box to the left is genuine
Counterfeit Line 2 lighters are heavier then real ones.

Counterfeit Line 2 lighters are heavier then real ones.
If there is no paint underneath the Cap for the refill valve, its almost definitely fake, though its possible to be a replacement with no color dot. All Line 2 Lighters have a yellow paint dot underneath the cap of the refill valve representing to use the gold Dupont Butane refill can (see picture below). If it comes with a brass butane adapter (unless it screws in) its probably Counterfeit. You should need to screw in the butane canister refill, and we (as well as ST Dupont) recommend to only use Dupont Butane gas in ALL ST Dupont Lighters.
The Cap to the Right is Authentic. If your LINE 2 cap doesn't look like the one to the RIGHT, ITS FAKE.
Its also possible for the paint to have chipped off inside the cap, but if that has happened, you should be able to find some pieces of the paint in the cap.
Real S.T. Line 2 lighters now retail for over $700, most $900 retail. If it NEW and cheap, its probably fake. If selling party calls it anything but 'ST Dupont' then its probably a fake lighter. Sellers do this to get around ebays keyword check.
The Sound when the lighter is opened should be a pleasant lasting sound, in my experience the Ping sound dulls with use. The counterfeit ST Dupont makes an awful metallic 'cling' which differs greatly from a real ST Dupont ping sound.
There is a screw holding a metal plate inside the top of the lid that can become loose. If you have a used ST Dupont its possible somebody has removed it to prevent it from ruining the sound of the lid when opened. If you hear a rattling when lifting lid then it could be this plate coming loose. All you need is a small flat head screw driver to tighten it. Though be very careful not to scratch anything while you are in there. Also turn down the flame adjuster as much as possible before sticking your face directly over the butane valve.
