LENEXA, Kan. -- Huge demand for the newest Royals jersey has spawned a fairly predictable problem: counterfeits. But retailers are saying they didn't expect the amount of complaints they'd receive for the fake gold-threaded gear.

The gold-trimmed jerseys are one of the hottest commodities in town, and any time supply can't keep up with demand, counterfeiters step in to take advantage.

But there are a few things to look for to make sure your jersey isn't a knock-off.

Authentic jerseys have a Majestic genuine merchandise heat seal tag along the back collar of the jersey.

That tag will also appear on the outside of the shirt, at the bottom.

And the one thing most counterfeiters haven't been able to replicate is the holographic drop tag.

FOX 4's John Pepitone got his hands on a counterfeit powder blue jersey, and at first glance, it looks to be the real deal. It even had the "authentic" tag on the outside.

But on closer inspection, the logo on the tag was from two years ago. Comparing it to a legitimate Royals jersey, the shirt's color wasn't even the same shade of blue. So buyers, just be vigilant.

So why should people care? If it looks pretty close, and it might be cheaper, then why not just buy the counterfeit?

Counterfeiters aren't just undercutting honest businesses. They're ripping off the Royals. Major league teams get a cut from the sales of all officially licensed gear.

So if you like your boys in blue, and want them to keep being a successful franchise, get the real deal.

Now that the Royals have announced that they will wear the gold jerseys on Friday night home games, Rally House has ordered a new supply of authentic jerseys that it expects to have by June. There's still a good supply of the gold trimmed caps.

In the last ten years, Major League Baseball has confiscated $6 million worth of non-licensed products.
