Fantasy chips are casino chips that are produced with a fictitious casino's name/emblem on them. They're often produced for events or movies (such as Rounders and a couple of the James Bond films) to give a realistic feel to the casino scenes/events in the film. They're not redeemable at any casino and have no inherent value. Fakes and counterfeits are chips that someone has produced to look resemble a real casino's chip. This are obviously produced for criminal purposes, are illegal, and could result in prosecution if you were to attempt to redeem them at the casino.
The first line of defense (assuming you don't want to end-up with one), is to simply ask each person you trade with or purchase from whether or not their chips are genuine. If they're a member of the CCA, they're obliged to be honest and disclose such information any way, but if they're not a member, at least asking will give you a line of defense if you later discover the chip is, in fact, counterfeit.
Perhaps the greatest resource in identifying counterfeits is the Fantasy, Fakes, and Counterfeits page at the CCA web site. Here you can see dozens of pictures of these chips.
Finally, if you suspect one of your chips is a fantasy or counterfeit, post a scan on The Chip Board and ask if anyone can ID it as such. You'd be surprised at how many people are out there that can help you.
