There's some easy ways to detect cheapish fakes. There's some more elaborate ones on the market, but not many.
1. Serial number. Stamped on bottom by hand, so IRREGULAR. 6-8 characters (numbers and capitals) at most.
2. "lack de chine" present on lighters that don't have any
3. Colour-code of required refill inside filling cap
4. initials of employee who made it behind the flint roller when you remove it.
5. Most popular models (diamond head, Lackue de chine) most likely to be fake.
Most important: price. Don't expect a real one new for under 250 US $.

s.t dupont lighters are the finest in the world *edit: though if by 'best' you don't mean 'most expensive', I own a s.t. dupont, and keep it in my drawer. I use a zippo daily. Wind-resistant, sturdy, easy to maintain, and always lights. Not overly expensive either, and a joy to engrave.
The most expensive lighter is made by the french luxury firm S. T. Dupont and sells for $79000. It comes in four varieties and includes 18karat white gold.
If you paid about 40 dollars for then yes they probably used real coins. If you paid 10 for then its probably a fake.
From my experience, I was able to carry a Bic lighter with me in my check in baggage.
The best way to check if a university is fake or genuine is to check its accreditation. Kingsbridge is accredited.
Only table lighters have any collectable value. Check on Ebay to see what they are selling for.
Check the fuses esp if more then one does not work
