Be on the lookout for super fakes. They're cracking down on counterfeit merchandise tied to the game and Rebecca Jarvis has E story. Reporter: This morning, officials warning super bowl fans everywhere, beware of fakes. According to homeland security, federal officials have already intercepted a record $20 million in fake gear and tickets. That's 15% more than last year when they seized over 17 million in fakes before the big game. What is it about the super bowl that makes counterfeiting prime time? Well, it's the event, I mean, it's probably the most watched event ever. Reporter: "Good morning America" going behind the scenes at the JFK international mail facility in New York where 700,000 packages arrive each day, inspecting a new shipment of fakes that's just come in. We see these NFL products, for example, coming in from China. That's a good indication it's counterfeit. Reporter: That's a red flag. That's a red flag. 85% of the counterfeit items that we encounter here at this facility are from China. Reporter: Federal officials here uncovering hundreds of thousands of dollars in phony NFL gear just days ahead of Sunday's game. The material here is plastic. It shouldn't be. That's all plastic. The stitching is off. See how the stitching is off. Reporter: Oh, yes. It's very poor quality. Reporter: Some of it including official looking NFL holograms. It says even engineered to the exact specifications of the national football league. Yes, not quite. Not quite. Reporter: But some still does slip through the cracks, so this morning officials are cautioning, when it comes to game day gear, it's buyer beware. If it's too good to be true, if you're getting $150 item for $40, it's because it is actually a counterfeit item. Reporter: If you're wondering just what happens to all the fakes they do find and confiscate, some of it does get destroyed or with the permission from the trademark holder, the NFL, the rest can be donated. Why not. To charity? That's really nice.
