Since the Indianapolis Colts won the Super Bowl, fake Colts memorabilia is already all over the Internet.

You can imagine the surge in Peyton Manning memorabilia after he was declared Super Bowl MVP. Peyton Manning memorabilia has always sold very well due to the popularity of Manning and how well he has done. This year's Super Bowl win pushed Peyton Manning memorabilia over the top.

Authentic Peyton Manning Indianapolis Colts memorabilia is very expensive. Manning learned the memorabilia game fast and has always charged high prices for his autograph. You'll find all kinds of rare memorabilia surfacing on auction sites like eBay -- memorabilia that allegedly comes directly from the big game and comes with stories like "I met Peyton Manning after the game" or in the locker room.

Beware, most of this Indianapolis Colts memorabilia is bogus. Remember, athletes like Peyton Manning charge almost $200 per autograph at collector shows. So if you see an item that seems too good to be true, it probably is. Stick to reputable companies -- most Peyton Manning memorabilia comes from Upper Deck and they charge top dollar for all their athletes -- Peyton Manning is no different.

Since current players rarely sign during the season, you'll often notice during the playoffs and the Super Bowl that it is very hard to find their memorabilia. So when you see a rash of memorabilia hit the market after the big game, then you know something is wrong.

You also know something is questionable if the seller says they got the autographed memorabilia in person (i.e. they hung out after the game and waited and got the autograph). Don't get me wrong, it is definitely possible to get memorabilia signed at the games, however it is extremely difficult to get multiple items signed this way.

Indianapolis Colts fans are no doubt overjoyed after the Super Bowl victory, but don't get duped into buying fake sports memorabilia.
