Hi

My father has just found a 25 year old+ S.T. Dupont lighter that he was given.

I just want to know if its genuine for one plus if so its model and value.

Serial No: 12FHD77

We do have an owners manual and dealer card inside that box.

Take a clear picture of the bottom and a few at angles with the cap open. To me it looks like a gatsby but I'm not familiar with that design

Hope this helps.

If it's that old, pretty sure it's real. Probably needs a servicing as the lighters just don't last forever. Seals dry, etc... Worth getting fixed, should be $100 to do so. You can a dual flame if you plan to use for cigars.

It is a beauty and a wonderful keep sake. I would get it serviced like Moses suggested and use it with pride!
Just don't lose it.

Bottom looks like it could be a Gatsby, or maybe a Ligne D.
Authenticity? Hard to say.

As for value, I have paid about $50-80 for Duponts in similar condition. If it had a recent service, you could add 110% the cost of the service plus $50-60. Regardless of value, you have a Dupont lighter! There are metal fuel adapters available and Dupont flints are not expensive.
