The NFL and Immigration and Customs Enforcement (ICE) say 400,000 counterfeit items since the last Super Bowl.
They say they have made 41 arrests.
The items would have been worth $39 million if they were real.
They say it is a problem because the money made off the items go towards narcotics, human trafficking and other illegal activity.
All the pictures below are of items seized in the Bay Area over the past few days.
