St Dupont Lighter Serial Number
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.
Thanks for that. I can't really tell from the pics, but is this a gold lighter? If so, I am going to go out on a limb and say it's real based on a few things: 1. The stamping of the letters is a bit crooked as it should be for a vintage Linge 1.

Vintage Ligne 1 Dupont's are rarely if ever faked 3. I have never seen a slotted fuel cap on a fake However, for resale value it's going to be very low. You don't have any papers or boxes with it. And since it's a combo laquer and gold (I am assuming gold) and not full gold, it's weight in gold value is decreased. It also looks as if it has been used pretty well.
Thanks, everyone for your interest. The lighter is gold in color with black inlay but It isn't marked with any metal content such as K (karat).

I'm assuming it is plated if any real gold at all. You think the gold parts could be solid even though it isn't marked?
I've seen some that were real gold but they were marked at the bottom of one of the narrow sides. I don't know if it works or not as I dont have fuel.
I does also need a flint. I figured out how to open the flint chamber but I don't have a flint either.

Any way to test it without fuel? Just curious what you mean $-wise by 'low' resale? It feels pretty hefty weight-wise. It certainly is a well made piece. I have an acid gold testing kit but I'm afraid to put any directly on the surface and risk any damage.

This forum has been very responsive and helpful. Thanks to all very much. I would be willing to bet it is only plated and not solid. The Ligne 1 editions are the entry level into the ST Dupont lighter line up. Used Ligne 1 lighters are fairly abundant and not really worth much on the open market, but it is probably worth more than what you paid for it. Just for the record though: The font stamp under the lighter is not what I am used to seeing on any Dupont I have ever come into contact with.
The script S T Dupont looks way off to my eye. If you contact ST Dupont and give them the serial number on the bottom, they can tell you without question if it is real or not. And yes, if theres a real ST Dupont anything, theres fakes out there as well including the Ligne 1.
